remove `pkg/registries`
Pull the trigger on the `pkg/registries` package which acted as a proxy for `c/image/pkg/sysregistriesv2`. Callers should be using the packages from c/image directly, if needed at all. Also make use of libimage's SystemContext() method which returns a copy of a system context, further reducing the risk of unintentionally altering global data.
