(krb5_get_forwarded_creds): honor

Browse Source 
KRB5_AUTH_CONTEXT_CLEAR_FORWARDED_CRED and create unencrypted
(ENCTYPE_NULL) credentials. for use with old mit server and java based
ones as they can't handle encrypted KRB-CRED. Note that the option
needs to turned on because if the consumer sends the KRB-CRED in clear
bad things will happen.
