[android] reject an out-of-range SSH port

Browse Source 
The port arrives as an int because gomobile cannot carry uint16 across the
Java boundary, so nothing rejected a value outside the valid range. It
reached strconv.Itoa and only surfaced as a dial failure, after the server
detection had already spent its timeout.
