Fix region sampling for secure layers

We were swapping a couple of boolean params when requesting
screenshots for region sampling, breaking region sampling for
secure layers in the process. Fix this by passing flags instead of
booleans in a long list of arguments and add a test to verify the
code path.

FLAG: EXEMPT bugfix
