nix-shell --pure: Let it work for any derivation
`nix-shell --pure` when applied to a non stdenv derivation doesn't seem
to clear the PATH. It expects the stdenv/setup file to do so.
This adds an explicit `unset PATH` by nix-build.cc (nix-shell) itself so
that it's not reliant on stdenv/setup anymore.
This does not break impure nix-shell since the PATH is persisted as the
variable `p` prior in the bash rcfile
fixes #5092
