New package: zoom-system-qt-5.0.403652.0509_1
Add package for zoom using system libraries (modelled after https://aur.archlinux.org/packages/zoom-system-qt/). This adds e.g. wayland support and removes doubled and possibly outdated qt libraries. However, since this might break if zoom isn't updating to a close enough qt release, it's better to keep zoom with included qt around as well.

A patch file from https://github.com/void-linux/void-packages/pull/21908.patch is attached
