Fix avd device name resolution with GNU netcat
Fix avd device name resolution with GNU netcat

Summary:
Device connection didn't work on Linux due to netcat behaving differently.
I also played around with the `nc` and `node-netcat` packages, but they would
either crash the node stack or fail to compile with Babel. Oh glorious
JavaScript world.
