Subject: Set CODEROOT dynamically in nix builds

This seems to be needed for git test to work, in particular the directory inside
the nix sandbox is like '/build/<name-of-checkout-directory>' which, in the case
of git test, is the name of the worktree that git-branchless uses to checkout
the commit under test. This is something like 'test-worktree-2'. So, I can't
hardcode anything there.
