Looking at the luarocks slackbuild, it already handles the case
where lua (5.4.x) and lua51 (5.1.x) are both installed. It has
REQUIRES="lua", and it autodetects lua51.

I didn't add luajit support, but it would be doable. Is it really
necessary though?

There shouldn't be 3 separate luarocks builds for the 3 possible lua
versions. We don't need the overhead.
