expensive as it may be it is more reliable check if the icon is actually
available than QIcon::isNull() (for system icons anyway)

this makes KIcon serializable by name (e.g. by KDBusMenuExporter) in
most cases, that however means lookup on the other end (if the icon pixmap
is not serialized it is essentially the same as calling QIcon::fromTheme()
on the other end of the serialization)
