media-libs/libsdl2: wire up libdecor support

Enable it with USE=wayland given upstream strongly recommend it
in their FAQ: https://github.com/libsdl-org/SDL/blob/main/docs/README-wayland.md#window-decorations-are-missing-or-the-decorations-look-strange.

(They've used stronger words on e.g. Twitter too.)
