diotest4: Skip test 3 and 14 for tmpfs

tmpfs in kernel v6.6 got support for O_DIRECT in e88e0d366f9c ("tmpfs:
trivial support for direct IO"). There is no reason for tmpfs to reject
direct IO of any size therefore follow the approach already used for
Btrfs, NFS and FUSE: skipping test 3 (odd count of read and write)
and 14 (read, write with non-aligned buffer).
