[1/2] kerberos: Add a stub for Kerberos5 Authentication Package.

Hi,


It's great to see kerberos support moving forward.

I do not think that a not functioning stub (when dependencies are 
missing) is useless. I added the stub because it was needed (and enough) 
for Office 2013 installer. The installer needs to register 
authentication info for its RPC server successfully. As long as no 
actual authentication is done (and installer also registers NTLM info, 
which is used in practice), a stub is enough.

That said, if EnumerateSecurityPackagesW will not return kerberos 
without libkrb5 available, libkrb5 will become a hard dependency of 
Office 2013 installer (and Office 2016 I guess, but I didn't verify 
that). It might be okay, but please take that into account in 
considerations.

Thanks,
Jacek
