Fix buggy test for the fchownat-deref bug.
* m4/openat.m4 (gl_FUNC_FCHOWNAT_DEREF_BUG): Create the dangling
symlink required for the run-test. Without it, this test would
always declare that fchownat doesn't work, and client code would
unnecessarily use the replacement function with fixed libc.
(gl_FUNC_FCHOWNAT): Eliminate a variable that wasn't initialized.
Reported by Greg Schafer.
