Matthew John Cheetham 8f21383178 gss-api: stub gss_inquire_context for debug builds
The GSS-API debug stub did not implement gss_inquire_context, so
the NTLM-detection logic in spnego_gssapi.c could not be exercised
without a real Kerberos environment.

Add stub_gss_inquire_context that returns the NTLMSSP OID when the
stub context is in NTLM mode and the Kerberos OID otherwise. Wrap it
behind Curl_gss_inquire_context so the stub is transparently
selected when CURL_STUB_GSS_CREDS is set.
