1. Bump versions on dependencies …

   dwrote-rs, freetype: Use a published crate rather than the github repository, so
       that the Firefox build system can vendor in the crate properly.
   offscreen_gl_context: Pick up a new version which doesn't require a libEGL
       dependency on linux. The change was made in
       servo/surfman#74
