Minor changes to fix a couple more warnings given by SonarCloud
static analysis.
Get the code coverage enabled, it wasn't running properly.
testrender: allow secret TESTRENDER_AA to override command line --aa
runtest.py: allow secret OSL_TESTSUITE_SKIP_DIFF to force skipping
the reference comparison step.
For analysis run, set TESTRENDER_AA=1 to keep the tests from being
prohibitively expensive, and OSL_TESTSUITE_SKIP_DIFF=1 to keep it
from failing because the aa=1 images are different.
