xz: Don't fsync directories on QNX

Browse Source 
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
