[PATCH BlueZ] obexctl: Add optional argument channel to connect command

[Luiz Augusto von Dentz <luiz.dentz@xxxxxxxxx>]

From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This adds a third argument to connect command so a channel can be passed
to CreateSession which is useful since it possible to force a specific
RFCOMM channel.
