GTK: Apply browser theme to TYPE_CONTROL windows

GTK: Apply browser theme to TYPE_CONTROL windows

This fixes the find bar view. I don't know what other, if any, UI
surfaces are affected.

Before this patch both the current and the MD findbar always use the
system theme, but this looks broken because the find bar is part of
the top browser Chrome. With this patch, the findbar will only use
the system theme if the whole browser is in GTK theme mode.
