upstream: add some knobs:

UNITTEST_FAST?= no     # Skip slow tests (e.g. less intensive fuzzing).
UNITTEST_SLOW?= no     # Include slower tests (e.g. more intensive fuzzing).
UNITTEST_VERBOSE?= no  # Verbose test output (inc. per-test names).

useful if you want to run the tests as a smoke test to exercise the
functionality without waiting for all the fuzzers to run.
