Fix KRB5_GC_CACHED for S4U2Self requests

In krb5_get_credentials_for_user(), always exit after the first cache
check if KRB5_GC_CACHED is specified.  Not making network requests
with this flag is more important than finding a post-realm-discovery
cached entry.

If KRB5_GC_CACHED is specified without a principal name, fail
immediately, as we cannot check the cache by certificate.
