Hmm, glibc 2.4 (first one with fchownat() support) has been released in
2006. I wonder if seven years is long enough and if we can get rid of
the wrapper now... Moreover I'm not sure what is the status of
alternative libc implementations.
There still may be enterprise distributions that still have older glibc
than that. Anybody out there?

This should not be removed but rather moved to the first lines of
setup() function and the TWARN should be changed to TCONF as:
tst_brkm(TCONF, NULL, "This test needs kernel 2.6.16 or newer"

Do not remove the option parsing code.

Make use of tst_tmpdir() here instead. And also drop the pid from the
test file names as the directory made by tst_tmpdir() is unique
allready.

Make use of tst_rmdir() here instead of the unlink and rmdir.
