[dev.typeparams] cmd/dist: disable -G=3 on the std go tests for now

Disable -G=3 tests on the std go tests, in order to see if -G=3 is
causing the flakiness for the dev.typeparams builder, as opposed to
other changes in typeparams branch. It's possible that -G=3 is using
more CPU/RAM that causes flakiness, as opposed to more specific bugs.
