[Linux] Get installed open-vm-tools packages before uninstalling

[keirazhang]

openSUSE 16.0 Beta release doesn't have open-vm-tools-desktop installed as it has no desktop. To avoid uninstalling non-existing package, this fix filtered out installed open-vm-tools packages, and then uninstall them.

ovt_packages list contains open-vm-tools-desktop when guest_os_with_gui, so here openSUSE 16.0 Beta release without desktop but getting parameter guest_os_with_gui to be set to True?

We check whether display-manager.service is running to decide guest OS has GUI or not. At present, openSUSE 16 has this service running but its desktop is not ready yet. So it added open-vm-tools-desktop into OVT package list.

Then the problem is setting parameter guest_os_with_gui according to the real situation.

The desktop issue would cause ovt_verify_status failure, and I will create another pull requests to update desktop detection by checking login session.

Uninstalled packages should not block the testing. We only need to uninstall whatever it is installed in the guest OS.

LGTM, thanks!
