github/workflows: use cross-platform-actions for freebsd

Since vmactions is basically a bootlooping disaster* with no signs of
life from upstream, let's try a different action instead and hope it
works better. We don't need to force the latest release channel, so
delete that part. Also make the pkg install just one command for
simplicity.
