MAINT-2168: fail with real message if required var PORT not set.

llhttpclient_test.cpp is only supposed to be run by test_llsdmessage_peer.py,
as specified in llmessage/CMakeLists.txt. test_llsdmessage_peer.py sets the
environment variable PORT before running INTEGRATION_TEST_llhttpclient. While
it's not yet clear under what circumstances INTEGRATION_TEST_llhttpclient
could find PORT not set (getenv() returning NULL), it's obvious that in that
case, the previous code might well crash. Make it at least fail with an
explanatory message rather than a mysterious large negative integer. In
theory, occurrences of that message could help us solve the underlying issue.
