s3-libsmb Don't ever ask for machine$ principals as a target.
It is never correct to ask for a machine$ principal as the target of a
kerberos connection. You should always connect via the
servicePrincipalName.
This current code appears to have built up from a series of minimal
changes, as the codebase adapted the to lack of a SPNEGO principal
from Windows 2008.
