Pass registered resource names to config.Validate (#423)

[fixes aws-controllers-k8s/community#1647]

Completes aws-controllers-k8s/runtime#117

This patch adds a tiny modification to the controllers `main.go` that
passes the resource names to `ackCfg.Validate` method.

Needs a new runtime release.
