core/mount: also remove default deps from /proc/self/mountinfo when it is updated

Browse source 
The dependencies tagged with UNIT_DEPENDENCY_MOUNTINFO_DEFAULT depend
on both /proc/self/mountinfo and corresponding .mount unit file.
Hence, if some information from mountinfo is updated, e.g. device mounted
on the path, we need to update the dependencies.
