tests: Add wrap for libusb_init and use it in dediprog test

Missing wrap for libusb_init has been discovered while working
on the test for raiden_debug_spi. Both dediprog (existing test) and
raiden_debug_spi (new test, see later in this chain) are using
libusb_init, so it definitely needs to be wrapped and added to io_mock.

Why tests worked before, without the wrap: my understanding is that
real libusb_init was called for dediprog test? Given that tests
definitely should not call any real libusb functions, wrap is needed.
