virttest.env_process: Use vm.instance in counter and vm_register_error_count in _store_vm_register()

Now we use vm.name in  counter and vm_register_error_count in _store_vm_register().
It could not work well in migration mode, which two vms have same name.

standalone_test: Enable only filter when listing tests

Currently when running with option `--list-tests`, we can use `--no`
to remove some tests, but we can't apply an `only` filter.

With this modification, we can apply an `only` filter by running
```
./run -t libvirt --list-tests --tests virsh.domuuid
```
to list only the tests you needed.

vm_xml: Update seclabel functions to support multiple seclabels

Current functions only support one seclabel in domain xml, while
domain xml support at least two seclabels in domain xml, depend on
security drivers, our testing is focus on selinux and DAC.

e.g.
...
  <seclabel type='none' model='dac'/>
  <seclabel type='none' model='selinux'/>
...

so, modify set_seclabel and get_seclabel functions use list contains
dict member as parameter and return.
