This is a bit odd (I first thought "Why not if toolkit_views?", but I guess we
don't want to compile this on Mac views either); hopefully it'll just become "if
(is_chromeos)" soon anyway, so I guess it's fine.

Yup, in fact ui_app_list_views_sources can then just be folded into
ui_app_list_sources, but we're blocked on having a build where we can test with
enable_app_list=0
