Alexander Goncharov d0fc4e76e1 tests: add basic lifecycle test for ch341a_spi
TEST=the following scenarios run tests successfully

1) ch341a_spi is enabled
result: all tests run and pass, including ch341a

2) ch341a_spi is disabled
result: ch341a_spi test is skipped, the rest of tests run and pass

3) libusb isn't presented in the system
result: tests for usb programmers are skipped, the rest of tests run
normally
