[WIP] tests: Add init-shutdown test for raiden_debug_spi
This patch adds a test for raiden_debug_spi and lots of
libusb wraps.
Marked as WIP because I feel my approach to libusb symbols
is questionable. The test is working though.
Another thing less-than-ideal is USB_DEVICE_ADDRESS, can
probably be done better.
BUG=b:181803212
