lua-rocks: update to version 3.9.2

## What's new in LuaRocks 3.9.1

* Fixed error message when Lua library is not found
* Fixed build of Windows binary
* A couple of minor feature additions:
  * API: `loader.which` has a new mode for searching `package.path/cpath`
    * Adds a new second argument, `where`, a string which indicates places
      to search for the module. If `where` contains `"l"`, it will search
      using the LuaRocks loader; if it contains `"p"`, it will look in the
      filesystem using `package.path` and `package.cpath`. You can use both
      at the same time.
  * `--no-project` flag can be used to override `.luarocks` project directory
    detection
