wl_shell no longer supported by compositors, hello example now broken

wl_shell no longer gets registered:

This breaks the hello example:

Weston reports this

[13:45:36.154] Note: support for the deprecated wl_shell interface is disabled. If a legacy client still needs it, it can be re-enabled by passing -Ddeprecated-wl-shell=true to Meson when building Weston.

Tested on weston 10.0 and mutter 42.0
