python3: drop deterministic_imports.patch

https://github.com/python/importlib_metadata/issues/489

Upstream discussion revealed that:

- the issue was happening due to a bug in setuptools

- the bug was fixed in setuptools 63 (I confirmed this: empty dist-info
directories no longer seem to trigger any issues if the patch is dropped)

- the patch would obscure any further issues of this kind instead of exposing them
for easy fixing, so they suggest we drop it and report if anything else pops up
