Reverts #2340

It seems like there were cache hits that dodged an important issue

This flag still cannot be flipped without breaking coverage it seems.

This was originally noticed on #3052 where the updated test //test/bzl_version:bzl_version_test failed.
https://buildkite.com/bazel/rules-rust-rustlang/builds/13085#019399fb-3319-4b50-b03e-c23ef1c3e8f4

Unfortunately, due to bazelbuild/continuous-integration#1838 no logs were captured but the issue is reproducible locally
