Bug 14507 Use checkpw to check password in Patron Info

Some devices are using patron information responses to validate
patron passwords to govern access to facilities as we
were using C4::Auth::checkpw_hash this only worked in a db password
context not other authentication routines.
The C4::Auth routines are not very consistent and there isnt a dropin
replacement for checkpw_hash this calls checkpw instead.
In a password only environment this behaves as the old version did
returning field CQ as Y if a valid password or no password is passed in
the patron info request and N if an incorrect password is supplied
It should also test against the appropriate authentication sources if
othere autrhentication schemes are in use

Tested this with a client who reports that this enables SIP authentication to work correctly with their LDAP server.
