Cannot use `runfiles.python` import path when running `bazel coverage`

# 🐞 bug report

### Affected Rule

compile_pip_requirements

### Is this a regression?

Not sure.

### Description

In some situations it is possible to get a conflict between the python module from the coverage package and the python package from the runfiles library. I would say this is due to the slightly risky use of "python" as a module/package name and the import `from python.runfiles import runfiles` in dependency_resolver.py.

## 🔬 Minimal Reproduction

```
cd examples/multi_python_versions
bazel coverage --incompatible_default_to_explicit_init_py //requirements:requirements_3_10_test
```

## 🔥 Exception or Error

Start by running `bazel coverage --incompatible_default_to_explicit_init_py //requirements:requirements_3_10_test` from `examples/multi_python_versions`. Read `rules_python~/python/private/pypi/dependency_resolver/dependency_resolver.py`, especially the `from python.runfiles import runfiles` import, and inspect the reported test log. Done means the coverage command completes without the `python.runfiles` import error.
