[CONTROLLER-504] Can't build sal-remoterpc-connector w/o a network interface that is up and has an IP address.

I was trying to work on a plane and so I had all of my network interfaces down and I got build errors looking something like this:

10:51:40.638 [main] DEBUG o.o.c.s.c.remoterpc.ServerImpl - Remote RPC Server is starting...
10:51:40.639 [main] DEBUG o.o.c.s.c.remoterpc.ServerImpl - Trying address /fe80:0:0:0:0:0:0:1%1

ServerImplTest.start_Call_ShouldCreateNHandlerThreads:150 Server is in illegal state. ServerHandler does not exist

After bringing up the wifi interface and attaching it to the in-flight AP, I was able to build without problems. We should really try to avoid dependencies like this if we possibly can.
