tests: tag the tests that do not work with multi-worker configuration

If the multi-worker default VPP configuration is triggered by
setting VPP_WORKER_CONFIG="workers 2", some of the tests fail
for various reasons.

It's a substantial number, so this change marks all of the
testsets that have this issue, such that they can be addressed
later independently.

Type: test
