Use containerd's platform package for platform checks. While the OCI
image spec requires the platform values to conform with GOOS and GOARCH
definitions of Go' runtime package, the values of uname are used by
convention. Supporting these values silences annoying false-positive
warnings.

Check the platform when looking up images locally. When the user
requested a custom platform and a local image doesn't match, the
image will be discarded. Otherwise a warning will be emitted.
Also refactor the code to make it more maintainable in the future.
