Skip inet_res_SUITE tests when external resolver does not start

E.g OpenBSD's (5.0) patched named does not allow itself to be
started without privilige separation, which is only allowed
for the superuser so test suites can not use that named.

Fix the shell script that starts named to detect early exit
from named and inform the Erlang code test suite what happened.
