Use mod_auth_gssapi instead of mod_auth_kerbgssapi

Change configuration on new installs only.

Enable GssapiLocalName so we have access to the local name in
REMOTE_USER and the full principle in GSS_NAME.

Enable GssapiSSLonly even though SSLRequireSSL is also set.
The belt and suspenders principla.
