Our customer wants to use the x-gvfs-notrash functionality to deal with NFS issues. See https://issues.redhat.com/browse/RHEL-2824. It doesn't work properly for NFS because GUnixMountMonitor doesn't see the mount options in certain cases.

This is because GUnixMountMonitor is not aware of the /run/mount/utab file changes. This file contains the userspace mount options (e.g. x-gvfs-notrash) among others. There is a problem when /sbin/mount.<type> (e.g. mount.nfs) helper programs are used. In that case, the /run/mount/utab file is updated later than the /proc/mounts file and thus the GUnixMountMonitor clients (e.g. gvfsd-trash) don't see the userspace options until the next mount-changed signal. See: https://issues.redhat.com/browse/RHEL-14607.

The https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3845 MR ports GUnixMountMonitor to use the libmnt_monitor API for monitoring. So the mount-changed signal is emitted after the /run/mount/utab change. Can we please backport that?
