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
