file and python dependents: add missing dependencies (#26785)

* py-magic: delete redundant package

This package is actually named py-python-magic (since the project itself
is "python-magic").

* New package: libmagic

* Py-python-magic: add required runtime dependency on libmagic and new version

* Py-filemagic: add required runtime dependency

* py-magic: restore and mark as redundant

This reverts commit 4cab7fb69e.

* file: add implicit dependencies and static variant

Replaces redundant libmagic that I added. Compression headers were previously
being picked up from the system.

* Fix py-python-magic dependency

* Update python version requirements
