Should we do anything about `getconf PATH`?

[abathur]

See this nixpkgs PR and its motivating issue for context:

• glibc: Fix _CS_PATH to include default profile NixOS/nixpkgs#94937

I doubt intervening is a priority since resholve should generally already be writing all of the invocations that would be resolving from this PATH anyways, but this PATH does still affect things we invoke in turn.

The simple thing to do is patch it out to something that just echoes a fixed PATH, but then we have to decide what that PATH is.

Would probably need to start with a census of wild usage.
