This commit limits which tests run on which ARCH to allow all tests to
pass on CI.
* Qualify the FTDI tests with (FTDI4222 AND USBPLAT)
* Qualify the IO init tests with (DETECTED_ARCH == "MOCK")
* Renamed all unit tests to start with 'test_unit_' to facilitate
grouping with tab completion (or any other type of sorting)
* Updated docker targets with new unit test target name
