sha1_file: set whence in storage-specific info fn

Move the setting of oi->whence to sha1_loose_object_info() and packed_object_info(). This allows sha1_object_info_extended() to not need to know about the delta base cache. This will be useful during a future refactoring in which packfile-related functions, including the handling of the delta base cache, will be moved to a separate file.
