DocBook-XSL: update to 1.79.2
https://github.com/void-linux/void-packages/pull/24849

Description:
Updates the docbook-xsl packages (namespaced and non-namespaced) to 1.79.1.

Adds patches to maintain compatibility with the old sourceforge URIs (from Debian).

Adds another random Debian/Fedora patch, because it seemed sensible.

I adopted the non-namespaced package, since the two packages are meant to be updated in tandem and I maintain the namespaced package.

I tested building with one namespaced and one non-namespaced package (iputils and eudev). Further testing is advised, although we could always revert (again).
