Fix the build on embedded linux

This patch:
    - adds required options to the embedded_linux.pri config
    - adds missing events_ozone.gyp:events_ozone_evdev dependency
    - fixes pkg-config not to pick host paths when cross compiling
    - implements missing functions of the OzonePlatform interface
    - updates the submodule to include fixes for chromium
