[PATCH 03/20] builtin/blame: convert struct origin to use struct object_id

["brian m. carlson" <sandals@crustytoothpaste.net>]

Convert struct origin to use struct object_id by applying the
following semantic patch and the object_id transforms from contrib:

@@
struct origin E1;
@@
- E1.blob_sha1
+ E1.blob_oid.hash

@@
struct origin *E1;
@@
- E1->blob_sha1
+ E1->blob_oid.hash
