This reverts commit 8355d42d.

After some discussion upstream [1] this patch turns out to be spurious.
It better gets reverted prior to a release.

SIGHUP is commonly used to instruct a daemon to reload its config. For
now we should handle it in virtlockd just like SIGUSR1, rather than
having it kill the process.

The virtlockd/libvirtd daemons had listed '?' as the short option
for --help. getopt_long uses '?' for any unknown option. We want
to be able to distinguish unknown options (which use EXIT_FAILURE)
from correct usage of help (which should use EXIT_SUCCESS). Thus
we should use 'h' as a short option for --help. Also add this to
the man page docs

The virtlockd/libvirtd daemons did not list any short option
for the --version arg. Add -V as a valid short option, since
-v is already used for --verbose.
