nativesdk-packagegroup-sdk-host.bb: Update host tools for wayland

The wayland-scanner host tool required to build weston is moved to the
wayland-tools package, so update the SDK host tools list accordingly.

Also, the weston build requires wayland-scanner.pc to find wayland-scanner,
so add wayland-dev.
