pkg/registry: drop pointer wrapper functions.

The new k8s.io/utils/ptr package provides generic wrapper functions,
which can be used instead of type-specific pointer wrapper functions.
This replaces the latter with the former, and migrates other uses of
the deprecated pointer package to ptr in affacted files.

See kubernetes/utils#283 for details.
