tests/dbus-runner: Add methods needed for taking control of a session

Browse Source 
This is needed if one wants to run the test suite parts that need KMS or
evdev access in a virtual machine.

However, only initiate these methods if the meta-dbus-runner.py program
was launched with --kvm, as it's only suitable for using while running
as root in a virtual machine.
