scene/layer_shell_v1.c: fix bug in width/height calculations

...in wlr_scene_layer_surface_v1_configure()

Reproduce bug with waybar by setting `"margin": 5,`
in ~/.config/waybar/config. It will result in the right edge of the panel
extending outside the edge of the output.

The bug can also be reproduced with gtk-layer-demo by anchoring
left/right/top/bottom and setting respective margins
