pack-objects: pass fullname down to add_object_entry()

Browse Source 
Instead of giving a hash for grouping, pass fullname to add_object_entry().
I want to add "do not try deltifying this object" bit to object_entry based on
the settings in .gitattributes, and hashing the name down too early would
interfere with that plan.
