[Buildroot] [git commit] luajit: point /usr/bin/lua to luajit if lua not selected

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=754a3cf860c1e5f398a76a61177f3acae91a999c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The luajit package is a provider of a lua interpreter, but does not install a
lua executable.  This is fine for scripts that explicitly invoke luajit, but
not so good for scripts that just need a lua interpreter and call lua.  This
mod creates a lua symlink so that the non-jit-specific scripts will still work.
