Make avahi startup more robust.

Browse Source 
If the hostname of the current virtualization machine
could not be resolved, then libvirtd would fail to
start.  However, for disconnected operation (on a laptop,
for instance) the hostname may very legitimately not
be resolvable.  This patch makes it so that if we can't
resolve the hostname, avahi doesn't fail, it just uses
a less useful MDNS string.
