[core] don't force downloading of Open Sans fonts

When a SymbolLayer doesn't have a text-font defined, we automatically add Open Sans/Arial Unicode MS. However, when the SymbolLayer is only used for rendering icons, it doesn't have text-field defined either. In those cases, we still force downloading Open Sans/Arial Unicode MS during offline pack creation. If the user doesn't use this font, this change should save ~15MB and a few seconds in download time.
