Removed CentOS 6 incompatible options from the sshd_config template

'AuthorizedKeysCommandRunAs' is the equivalent of the 'AuthorizedKeysCommandUser' option in the version of OpenSSH that ships with CentOS 6.5

'VersionAddendum' is not a valid option so sshd fails if it's included.

The following are error messages reported without these changes:

```
NOTIFIED: [generic/sshd | restart sshd] ***************************************
failed: [config] => {"failed": true, "item": ""}
msg: /etc/ssh/sshd_config: line 47: Bad configuration option: AuthorizedKeysCommandUser

NOTIFIED: [generic/sshd | restart sshd] ***************************************
failed: [config] => {"failed": true, "item": ""}
msg: /etc/ssh/sshd_config: line 105: Bad configuration option: VersionAddendum
/etc/ssh/sshd_config: terminating, 1 bad configuration options
```
