The default linker option with Bullseye appears to now set
as-needed, so as the core doesn't call into mmal_vc_client
it is viewed as unnecesary, missing that mmal_vc_client has
a constructor that registers functions with the core.
Move the registration of the component supplier to the core_init.
The linker is therefore satisfied that mmal_vc_client is used,
and actually links to it.

This allows Picamera to work again.
