`PIP_REQUIRE_VIRTUALENV` breaks installation of dependencies from `.tar.gz` URIs

# 🐞 bug report

### Affected Rule

This might be related to how `wheel_installer` is invoked.

### Is this a regression?

No, 1.4.1 and https://github.com/bazel-contrib/rules_python/pull/3115 (commit https://github.com/bazel-contrib/rules_python/commit/75871bbb9b33723c60565de0d7959c3262f87337) have this problem. 1.5.0 and 1.5.1 likely also have this problem, but I can't confirm since `.tar.gz` installation is broken in those releases (see #3131).

### Description

Running a `py_test` target with `PIP_REQUIRE_VIRTUALENV` set to `true` results in errors if one of the dependencies is installed from a `.tar.gz` URI.
Adding `common --action_env PIP_REQUIRE_VIRTUALENV=false` to `.bazelrc` can be used as a workaround.

## 🔬 Minimal Reproduction

`export PIP_REQUIRE_VIRTUALENV=true` in the shell. Then follow the minimal reproduction steps in #3131 but for `rules_python` 1.4.1 or https://github.com/bazel-contrib/rules_python/pull/3115 (commit https://github.com/bazel-contrib/rules_python/commit/75871bbb9b33723c60565de0d7959c3262f87337). 1.5.0 and 1.5.1 would fail with a different error due to #3131.
