  lib/krb5: fix srv_find_realm invalid gTLD test

In srv_find_realm() the conditional for testing whether an entry
is the invalid gTLD response was inverted.  Refactor the conditional
into a helper function is_invalid_tld_srv_target().  Use the helper
to simplify the conditional making it easier to confirm that the
test is correct.
