Revision 383668

MFH: r382722

Obtain a credential on login with KDM4

PAM_SETCRED(3)'s second parameter does not default to PAM_ESTABLISH_CRED on
FreeBSD, so explify it, as was proposed on the forums[1] back in decembre.

Bump port revision as this commit changes the runtime behavior of the
installed port.
