Fixes from Openwall patch shadow-4.0.4.1-owl-chage-drop-priv.diff:
* src/chage.c: Remove cleanup(). pw_lock is never called. Replace
cleanup(2) by spw_unlock and remove the calls to cleanup(1).
* src/chage.c: Remove variable pwrw. It is always set to 0. The
password database is always read only.
* src/chage.c: Make chage -l also drop the saved GID.
* src/chage.c: Prefer setregid/setreuid to setgid/setuid.
