texlive: make tlmgr work and split libsynctex
tlmgr was attempting to lookup a relative path to /usr/bin, while it
expects to be in /usr/share/texmf-dist. Instead of symlinking it, create
a smallscript to run it from the correct location.

A patch file from https://github.com/void-linux/void-packages/pull/24300.patch is attached
