Subject: [PATCH] Bug 21547: Use set_password in opac-passwd and remove sub
 goodkey

Remove sql statement to change password by calling set_password.
Remove sub goodkey by calling C4::Auth::checkpw_hash.
Adding the scalar before param Oldkey (from bug 21036).

Rebased on top of 21178 (using set_password instead of update_password).

Test plan:
Try to change password in OPAC with good and bad pw.
