[Buildroot] [PATCH v2] luajit: point /usr/bin/lua to luajit if lua not selected

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.

Changes v1 -> v2:
   - Remove BR2_PACKAGE_LUA conditional, as suggested by Yann Morin.
     (Diverges from python3 precedent, but saves a test.)
   - Drop some detail from the commit log that might be misinterpreted.
