Installing luajit 2.1 gives outdated version from 2017

[tobil4sk]

I had some crashes when running luarocks (specifically in luasec, see below) using luajit 2.1 on linux arm64. Hererocks is installing 2.1.0-beta3, which is from 2017 and is very outdated and has issues.

According to the luajit release policy:

LuaJIT uses rolling releases. The authoritative origin is the git repository from this site. You should regularly pull from the selected git branch to get the latest fixes and developments. No release tarballs or binaries are made available.

https://luajit.org/status.html#release

Workaround is to change -j=2.1 to -j=@v2.1, but it is probably best for hererocks to give a default luajit install based on the luajit release guidance.
