kernel.bbclass, module.bbclass: Make update-modules optional
The update-modules mechanism is something of a historical relic and it isn't entirely clear that it has a great deal of value nowadays. Also, it causes a problem when building a read-only rootfs since update-modules itself refuses to configure offline. Allow DISTROs to circumvent this whole thing by declaring (via DISTRO_FEATURES) that they don't wish to use update-modules. This is backfilled for existing distributions and will have to be marked as CONSIDERED by those who actually don't want it.
