libxcb is in recipes/wip/x11/ which is not safe upstream ownership for
Red Bear shipping decisions. KWin on Wayland does not need X11 — the
recipe already builds with -DKWIN_BUILD_X11=OFF -DKWIN_BUILD_X11_BACKEND=OFF
and the build script removes #include <xcb/xcb_cursor.h>. The libxcb
dep was leftover from a full X11+KWin build and is not required for
the Red Bear Wayland-only compositor path.
