virsh: avoid bogus description

https://bugzilla.redhat.com/show_bug.cgi?id=682121

Gettext reserves the empty string for internal use, and it must
not be passed through _().  We were violating this for commands
that (for whatever reason) used "" for their description.

* tools/virsh.c (vshCmddefHelp): Don't translate empty string.
