[libvirt] [PATCH 2/2] Shorten domain name for automatic coredump
If the domain name is long enough, the timestamp can prolong the
filename for automatic coredump to more than the filesystem's limit.
Simply shorten it like we do in other places. The timestamp helps with
the unification, but having the ID in the name won't hurt.
