As with the previous PR, this PR takes the compiletest code for discovering an “ambient” cdb in the user's path, and moves it to bootstrap.

The discovery code is indeed questionable, but improving it is out of scope for this PR.

As with the previous PR, this PR takes the compiletest code for discovering an “ambient” `cdb` in the user's path, and moves it to bootstrap.

The discovery code is indeed questionable, but improving it is out of scope for this PR.
