meson.build: require xwayland version 21.1.9 for xwayland support

This and later xwayland releases ship fixes for drm leased devices
causing lags in Chromium and Electron based applications. We used
to work around the issue by simply not sending drm leases to xwayland
but we can now rely on the fixes being widely available.
See #553 for more information.
