Subject: [PATCH] screenshot: Don't pick up rubberband style from GTK

Selecting a screen area for a screenshot isn't the same as selecting
items in an icon view, so there's no strong rationale for picking
up the style from GTK. We stopped doing that for other elements like
tile previews long ago, so just use our own style here too.
