    pam-exherbo,pam-redhat: avoid password-auth/common-auth
    
    In theory sending the password to them could be beneficial.
    If for instance, they have pam_krb5 or pam_ecryptfs or pam_sss.
    
    In practice, the stacks will fail if the passwords don't match,
    and prevent autologin from continuing.
    
    This commit just sidesteps them for now.  Eventually,
    authconfig/et al, will need to get updated to accomodate us.
