Reland "Sandbox html_viewer on Linux."
This fixes a midair collision with a file move.
This creates a font_service which does the same role as
font_config_ipc_linux.cc does in content/. This lets us sandbox the
html_viewer, while still being able to communicate with fontconfig.
Also prewarms the ICU timezone data, along with doing all the
prewarming that's done in the core_services sandbox.
