selftests/filesystems: check that a mount namespace file on top doesn't bury a mount
Add a test for moving a mount with a mount namespace file on top of it:
- S, a bind mount of a file, with a newer mount namespace's file on top
- A shared with a slave B that has Q on B/file
- S moved onto A/file, its copy lands on B/file below Q
B/file keeps reading Q and once Q is unmounted it reads the copy.
