Remove incorrect logic from GetFullyQualifiedName()
Remove incorrect logic from GetFullyQualifiedName()

I think this logic was originally added with the assumption that any
hostname with a dot in it was an FQDN. I believe this is incorrect. The
hostname is the hostname regardless of included dots, and getting the
FQDN amounts to always querying for the canonical name.
