    xz: Don't fsync directories on QNX

    On QNX calling fsync on a directory fails with EINVAL. This causes the
    following test failure:

        $ cat tests/test_suffix.sh.log
        /data/home/root/xz-5.8.2/src/xz/.libs/lt-xz: suffix_temp: Synchronizing the directory of the file failed: Invalid argument
        Failed to decompress a file with a suffix set in raw format
        FAIL test_suffix.sh (exit status: 1)

    Closes: https://github.com/tukaani-project/xz/pull/216
