chromeos: copy command line switches to ash services

Ash related services, such as shortcut-viewer, create various objects that
read command line flags (such as ui::Compositor). This makes such services
copy the command line flags from chrome. Long term we shold move to a whitelist,
but shorterm not copying all flags is causing display problems for some devices.
