tests: Add more firmware selection coverage

This new test case covers the scenario in which the user
specifically asked for a read/write pflash image.

From the output files, we can see that the firmware selection
algorithm has picked a ROM image, which demonstrates the
presence of another bug. We're going to fix it with an upcoming
commit.
