Remove Gold service account from -dev bots

Removes the chrome-gold@ service account from
android-kitkat-arm-rel-swarming and
android-marshmallow-arm64-rel-swarming, which run tests on
chromium-swarm-dev. This is a temporary fix to prevent task triggering
from failing while a -dev version of chrome-gold@ is created.
