Make symbolic breeze icons be white when theme is breeze dark

I did not fully understand how it works, but now, when e.g. Dolphin or Konsole
are dark, light icons are used, when they are light, dark icons are used.

Inherinting hicolor does not make sense, because specification [1] forces and and because breeze* inherit it themselves.
