fastmodel: Check early for license server issue

We have a setup that requires manual startup of an ssh proxy to
access license server, and without that, gem5 takes about a minute
until the license checkout times out (until then, it's unclear
why nothing is happening).

We asked ARM for a way to decrease timeouts, but that doesn't
seem to be easy to do.
