uuu: usb_otg_path can be provided using command evaluation
Enable "on worker" uuu_otg_path configuration instead of modifying devices definitions located on the master.
Examples: Before this change, the LAVA device dictionary contained static uuu USB ID, like: {% set uuu_usb_otg_path = '1:324' %}
With this change, the dictionary can contain a command that will actually return this string, eg: {% set uuu_usb_otg_path_command = ['board-control', 'imx8mq-evk-01', 'extra', 'uuu_otg_path', '--silent'] %}
In this example, board-control is a tool that reads a cfg file on the worker, and returns the uuu string. The cfg file contains the actual uuu USB ID.
