Detect unsupported -U flag and fail fast with a clear error
start() now checks whether ubridge exited immediately after launch. An
old ubridge build that does not understand -U exits with a non-zero code
right away; surface the reason from ubridge.log instead of waiting for
connect() to time out 10s later with a confusing "couldn't connect" error.
