xsel: fix dead distfile and upstream webpage
Fixing upstream and distfile download links

Found this as a possible "changelog":

- https://raw.githubusercontent.com/kfish/xsel/master/release_notes/xsel-1.2.0.txt

I wasn't sure if I should added it being a separate file per release

A patch file from https://github.com/void-linux/void-packages/pull/39043.patch is attached
