Bug#1038805: gnubiff: Depends on unmaintained gamin

This package has a Depends or Build-Depends on gamin, which is unmaintained
upstream (see #1008205).

For software that already depends on GLib, GFileMonitor
(g_file_monitor_file(), g_file_monitor_directory(), g_file_monitor())
is a good replacement.

We shouldn't really be shipping gamin in Debian 13, so this is likely to
become release-critical in future.

Thanks,
