selftests/landlock: Use an actual chardev for MAKE_CHAR audit test

Browse Source 
By passing a (0, 0) device number, the audit test for
LANDLOCK_ACCESS_FS_MAKE_CHAR was accidentally creating a whiteout object
rather than a char device.  In preparation to treating whiteout objects
differently, use an actual character device instead.
