lrcalc: update to 2.1, rebuild sagemath-9.5
This PR updates lrcalc to 2.1, which will be required for sagemath 9.6.

This needs that we rebuild sagemath 9.5 with a few changes:
 - add a new python package `python3-lrcalc`
 - patch sagemath 9.5 so it can use the new version of lrcalc (via python3-lrcalc)

Unrelated to that, I added two patches to sagemath which fix doctests after upgrades of ipython to 8.0 and scipy to 1.8.

A patch file from https://github.com/void-linux/void-packages/pull/36209.patch is attached
