    Chromium patch to fix shared_library build.

    This patch adds needed changes in Chromium side to fix
    component=shared_library build for Ozone-Wayland.

According to the patch's author, this patch was not upstreamed because the
ozone-wayland code base is undergoing some refactoring that will make it
unneeded in the future.
