Drop pkg/dynamicmapper/fake_discovery.go

pkg/dynamicmapper/fake_discovery.go was originally implemented as a copy
of k8s.io/client-go/discovery/fake because the original client-go
implementation returned `nil, nil` for some methods.

However, this has been fixed in client-go, so there is now no need
to copy this fake implementation here.
