Subject: rm: fix --one-file-system regression due to fts conversion

* src/remove.c (rm_fts): Fix incorrect comparison of
device and inode numbers.
* tests/rm/one-file-system2: Add a separate test so
that it can be run as a normal user (It doesn't need to mount).
* tests/Makefile.am: Reference it.
* NEWS: Mention the fix.
Reported by Jan Larres.
