dediprog: Init-shutdown test for dediprog

Browse Source 
This patch adds mocks for libusb functions. To avoid dependency on
libusb.h, libusb symbols for context and device handle are redefined.
Real libusb functions are never called in tests anyway, cmocka wraps
work with this without complaints.

BUG=b:181803212
TEST=builds and ninja test
