[OE-core] [PATCH] wayland: only build the scanner in wayland-native

[Ross Burton]

We only build wayland-native for the scanner, so disable the bits we don't
actually need.  This gives us a small speed up but importantly should allow
wayland-native to compile on older hosts such as CentOS 5 which currently fails.
