Python 3.10 prints a warning when it sees `distutils` used, so let's avoid using `distutils` in the "common Mach code" that runs on every Mach call. Note that this change will also fix the `SetuptoolsDeprecationWarning` that shipped on `setuptools>=58.3.0`, since our usage of `distutils` was calling a `setup.py install` under the hood.
