Issue:
ios_facts: Tunnel interface MAC address shows IP address/Prefix
<!---
Verify first that your issue/request is not already reported on GitHub.
THIS FORM WILL BE READ BY A MACHINE, COMPLETE ALL SECTIONS AS DESCRIBED.
Also test if the latest release, and devel branch are affected too.
ALWAYS add information AFTER (OUTSIDE) these html comments.
Otherwise it may end up being automatically closed by our bot. -->

##### SUMMARY
<!--- Explain the problem briefly -->
When running ios_facts to gather information on interfaces, a tunnel interface MAC address shows up as a IP address/prefix, such as `10.10.10.1/30` instead of null

##### ISSUE TYPE
 - Bug Report

##### COMPONENT NAME
<!--- Insert, BELOW THIS COMMENT, the name of the module, plugin, task or feature.
Do not include extra details here, e.g. "vyos_command" not "the network module vyos_command" or the full path-->
ios_facts

##### ANSIBLE VERSION
<!--- Paste, BELOW THIS COMMENT, verbatim output from "ansible --version" between quotes below -->
```
ansible --version
ansible 2.5.3
  config file = ../Documents/Ansible/ansible.cfg
  configured module search path = [u'../Documents/Ansible/library']
  ansible python module location = /Library/Python/2.7/site-packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 2.7.10 (default, Oct  6 2017, 22:29:07) [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)]
```

##### CONFIGURATION
<!--- If using Ansible 2.4 or above, paste, BELOW THIS COMMENT, the results of "ansible-config dump --only-changed"
Otherwise, mention any settings you have changed/added/removed in ansible.cfg
(or using the ANSIBLE_* environment variables).-->
```
ANSIBLE_SSH_ARGS(../Documents/Ansible/ansible.cfg) = -o ControlMaster=auto -o ControlPersist=60s -o UserKnownHostsFile=
DEFAULT_MODULE_PATH(/Users/jvanderaa/Documents/Ansible/ansible.cfg) = [u'../Documents/Ansible/library']
HOST_KEY_CHECKING(../Documents/Ansible/ansible.cfg) = False
```
##### OS / ENVIRONMENT
<!--- Mention, BELOW THIS COMMENT, the OS you are running Ansible from, and the OS you are
managing, or say "N/A" for anything that is not platform-specific.
Also mention the specific version of what you are trying to control,
e.g. if this is a network bug the version of firmware on the network device.-->
MacOS --> IOS

##### STEPS TO REPRODUCE
<!--- For bugs, show exactly how to reproduce the problem, using a minimal test-case.
For new features, show how the feature would be used. -->

<!--- Paste example playbooks or commands between quotes below -->
```yaml
- name: Check facts
  connection: network_cli
  hosts: ios
  gather_facts: no
  become: yes
  become_method: enable

  tasks:
    - name: IOS>> Get facts
      ios_facts:
        gather_subset: all

    - name: DEBUG>> Print facts
      debug:
        msg: "{{ ansible_net_interfaces }}"
```

<!--- You can also paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- What did you expect to happen when running the steps above? -->
The information looks correct on physical interfaces. Virtual tunnel interfaces (`interface tunnel`) shows information that shouldn't be there.

##### ACTUAL RESULTS
<!--- What actually happened? If possible run with extra verbosity (-vvvv) -->

<!--- Paste verbatim command output between quotes below -->

I dug a little bit into the .py file referenced by the bot. Perhaps changing the search string to `, address is` may be able to catch a MAC address better. Not sure if that would hurt other interfaces if the modification is made unfortunately.
