fix: add support for bubt to another flash

       - Added a wrapper to the interface bubt functions which chooses
         the desired bubt interface according to an argument to the
         bubt command.
       - Current bubt usage is bubt [file_name] [destination_interface
         [load_from_usb]]
       - SYSTEMSW-1303
