Don't backup Build objects
Don't backup Build objects

The information required by OSBS is fully stored in BuildConfig and
ImageStream objects. Additionally, the Build objects are only restored
if they don't have a BuildConfig associated with them. Those are scratch
and isolated builds which we care very little about backing up in OSBS.
