[libvirt] [PATCH 2/2] qemu: Report less errors on driver startup

[Martin Kletzander]

It is not a problem at all if the `tss` user/group does not exist, the code
fallbacks to the `root` user/group.  However we report a warning for no reason
on every start-up.  Fix this by checking if the user/group actually exists.
