xbps-src: work around autodeps removal needing multiple passes
This code is not good at all (it's a terrible hack), but for the time being it solves the issue with `xbps-remove` not removing all obsoletes and needing multiple passes. Proper solution should be done in xbps, but I thought this could at least mitigate the problems for the time being.

A patch file from https://github.com/void-linux/void-packages/pull/15679.patch is attached
