Ash network icons: Remove unused label code and strings

In the new feature pod tray re-factoring, some strings and code that are
no longer in use got left behind, this cleans them up.

network_icon::GetLabelForNetwork was only getting called with icon_type
ICON_TYPE_MENU_LIST, and GetDefaultLabel was unused.
