[usb_gadget p08] Package the USB gadget framework for easy distribution.

This software package will need to be uploaded to the test hardware.
Python can easily run code out of a zip file. The package hash is saved
to verify integrity and as a versioning mechanism to allow tests to
ensure that they are running against a device with the expected software
version.
