core.modulemanager: Locate resources of LuaRocks-installed modules Extra non-code files included with a `copy_directories` directive in a LuaRocks manifest will be copied into a per-module and per-version directory under /lib/luarocks/ and all this is there to dig that out so it can be used in e.g. moduleapi :load_resource().
