Don't use any IPC pipe when in console-only mode or in a LOKit-based program

There is by definition no reason to do any IPC in those cases. Each program
running LO code in such a mode is independent from any other.

Do as before for Android, though, I don't have the patience now to check
whether we actually need the pipe on Android for some reason.
