Revert "Do not try to fchown() to uid -1 and gid -1."

This reverts commit c4f643b9fca4c4487ef74e4e6cd5b61a26025698, which
fixed a failure introduced by commit
f95ba548a286b17c260cc168715a9d0d441b14a6 which was reverted in
dd1dbff095629118e73a48a2a6008f03418a07f6.

(uid_t)(-1) and (gid_t)(-1) are perfectly valid parameters to
chown()/fchown() back to POSIX.1-2001 at least.
