......................................................................

Add unit test to run init/shutdown for dummyflasher.c

I plan to do this for all drivers in programmer table, one at a time. Dummy
is the first and the easiest.

After this was rebased on the top of memory checks
https://review.coreboot.org/c/flashrom/+/51243 , dummy has been discovered
to leak memory on shutdown, so I fix it here.

TEST=builds and ninja test
BUG=b:181803212
