libvpx5: remove package.
https://github.com/void-linux/void-packages/pull/43767

Description:
libvpx5 isn't used by any package at the moment. I don't think it's necessary to have a unversioned libvpx package anymore, so I removed it too, but I'm also okay with changing it to point to either libvpx6 or libvpx7.
