Don't exclude quite so much in a no-sock build

We were excluding more code than we needed to in the OCSP/HTTP code in
the event of no-sock. We should also not assume that a BIO passed to our
API is socket based.

This fixes the no-sock build

 It succeeds immediately if B<max_time> == 0 (which means no timeout given).
