Peter Marheine 47f4c18260 tests: add init_shutdown test for realtek_mst_i2c_spi
This can catch regressions like the earlier one in this programmer that
caused initialization to always fail. Requires support for mocking POSIX
file I/O functions because the programmer does ioctls on the opened
file.

TEST=ninja test
