[PATCH] oe-init-build-env-memres: Fix automatic port usage

[Richard Purdie <richard.purdie@linuxfoundation.org>]

The use of an automatic port wasn't working correctly since the server
was never getting started when port == -1. This fixes things so the
server is started when port is not specified (i.e. automatic) ensuring 
this happens before BBSERVER is set.
