Many rpm tests are not running under bazel 7 (bzlmod)

Now that bazel 7 is the default for CI, and we are using bzlmod, the toolchain finder does not work. Worse than failing, they just silently skip, so it's as good as not having the tests.

do you have a bit more context on where you're encountering this? I ran across this while pushing another PR and decided to check it out a bit, but I'm not encountering this when I'm running locally nor in my latest PR.

I think the bzlmod extension that finds the toolchain is just wrong. I implemented it in a hurry and may have just missed.
