tests: Split flashrom tests into two executables
The reason for splitting: some tests need to wrap spi_send_command, some other tests (specifically the tests in the next patch in this chain) need a real spi_send_command.
Cmocka offers a capability to call __real_spi_send_command to call a real function and bypass the wrap. However, the function in question, spi_send_command, is not called in tests explicitly. There is no clear way to say "for this one test use the wrap, for other tests use real".
There is one test file spi25.c which needs spi_send_command to be wrapped, and this test file is extracted into a separate executable in this patch. The rest of existing tests don't care about spi_send_command. However in the next patch new tests are added, and they need spi_send_command real. The approach used here is: use real function unless it is required to mock, so all tests that don't care go into the executable with the real spi_send_command.
