Can we please keep the tests where we check that -1 does not change the
value and where we asert that the previously set value is still there
after the fchown call?

We may as well add a check that fchown(fd, -1, -1) is no-op.

This produces a bit ugly output, what about adding format string and
parameters like:

	TST_EXP_PASS(FCHOWN(fd, tc[i].uid, tc[i].gid),
	             "fchwon(%i, %i, %i)", fd, tc[i].uid, tc[i].gid);

I guess I will push a similar patch that fixes this for fchown04 as well.

We really have to check if the fd has been opened, since the test can
exit in any SAFE_MACRO() so this has to be:

	if (fd > 0)
		SAFE_CLOSE(fd);


Other than these this is a nice cleanup.
