Subject: [PATCH] fix: fallback to /usr/bin/env if env is not in PATH

This fixes an issue where the bootstrap script would fail if env was
not in the PATH, which is the case on NixOS. The script now checks if
env exists, and if not, falls back to /usr/bin/env.

Fixes https://github.com/bazel-contrib/rules_python/issues/3575
