make specs-go a module

This should allow to import CDI spec structures without adding
a lot of CDI runtime deps.

It should partly fix #97 and allow Kubernetes to refer this module directly.
There are at least 2 places in the k/k codebase that would benefit
from this change:
- this can be replaced by the specs-go import:
  https://github.com/kubernetes/kubernetes/blob/master/test/e2e/dra/test-driver/app/cdi.go
- this can import specs-go and use JSON marshalling instead of
  quite ugly approach it uses to write CDI files:
  https://github.com/kubernetes/kubernetes/blob/master/test/images/sample-device-plugin/sampledeviceplugin.go#L237
