[cluttermm] Script::add_search_paths(): Use std::string for filepaths.

[Murray Cumming <murrayc src gnome org>]

commit ded8718c0ff17044c04890f21922abdb9f8f75ba
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Apr 11 10:25:22 2014 +0200

    Script::add_search_paths(): Use std::string for filepaths.
    
    * clutter/src/script.[hg|ccg]:
      Also avoid this g++ compiler warning:
      ISO C++ forbids variable length array 'searchPaths' [-Werror=vla]
    
      This shows the need for this patch in cogl to avoid a warning:
