Remove revoke-sudo from storlets, trove functional

The I670641b676231233f1dd583ea36421f8ffef8f8e change incorrectly
added a revoke-sudo macro to the gate-storlets-functional and
gate-trove-buildimage-{datastore} jobs which did not previously have
it, so remove it to get them working correctly again. It also added
one to dev-zuul-coverage, but I expect that was missing as an
oversight so not undoing it here.
