[OXT-43] xenmgr: Remove Dbus matches on VM delete

OXT-43

Add functionality to removeVm such that we invoke new functions defined in libxch-rpc
to make RemoveMatch calls to DBus.  This is a fix for xenmgr maxing out on dbus rules
during VM creation.

Thought I dealt with the whitespace when I was cleaning up the changes before I committed them.  Guess not, I'll be sure to address that.
