use free_mount_entry from gnulib instead of rolling our own

gnulib.git added the me_mntroot element in
commit c6148bca89e9465fd6ba3a10d273ec4cb58c2dbe,
so we would leak memory during filesystem refreshes as a result :x
Use the gnulib-provided API (free_mount_entry) instead of freeing
elements ourselves.
