0.4.1: Fix regression with virtual hosting (or something)

This version fixes a bug where, when using a server that had two domains
on one IP, the domain that wasn't on the server cert threw a 53 error.
The fix was simple: I added the -servername parameter to the openssl
invocation in gemini_request, which I'd had earlier but removed because
of my (apparently mistaken and/or hallucinated) reading of some manual
that stated -servername was automatically given if -connect stated the
server.

At any rate, the regression should now be fixed.  It at least works with
the one site that was causing problems.
