gtick: remove package
https://github.com/void-linux/void-packages/pull/41442

Description:
GTK2, abandoned since 2014

There is now [Metronome](https://gitlab.gnome.org/World/metronome) that we don't have packaged, but it's installable from flatpak. @thypon If you want to, I can package it. I would like you to approve this PR before merging this because you are the maintainer.
