Python: query distutils to find site-packages directory (#24095)
Third-party Python libraries may be installed in one of several directories:

1. `lib/pythonX.Y/site-packages` for Spack-installed Python
2. `lib64/pythonX.Y/site-packages` for system Python on RHEL/CentOS/Fedora
3. `lib/pythonX/dist-packages` for system Python on Debian/Ubuntu

Previously, Spack packages were hard-coded to use the (1). Now, we query the Python installation itself and ask it which to use. Ever since #21446 this is how we've been determining where to install Python libraries anyway.

Note: there are still many packages that are hard-coded to use (1). I can change them in this PR, but I don't have the bandwidth to test all of them.

* Python: handle dist-packages and site-packages
* Query Python to find site-packages directory
* Add try-except statements for when distutils isn't installed
* Catch more errors
* Fix root directory used in import tests
* Rely on site_packages_dir property
