Subject: [PATCH] Girocco/Config.pm: carefully add to $git_daemon_host_list

When adding the various names for localhost to $git_daemon_host_list,
be careful and avoid adding something that's already in the list.

It doesn't hurt for the same item to be listed more than once, but
it is trivially less efficient and it also looks sloppy.
