x11-wm/labwc: add new port
Labwc is a wlroots-based stacking compositor for Wayland.
It has the following aims:
- Be light-weight, small and fast
- Have the look and feel of openbox albeit with a smaller feature set
- Where practicable, use clients to show wall-paper, take screenshots, and so on
- Stay in keeping with wlroots and sway in terms of approach and coding style
