Subject: [PATCH] build: install lua from the os package repository (#5655)

- Install lua and luarocks from the OS package repository instead of
  manually downloading them. Also the luarock fork looked
  unmaintained.
- Remove luarocks from the image after installing lua packages because
  it's not needed after that
