bulk-checkin.c: store checksum directly

finish_bulk_checkin() stores the checksum from finalize_hashfile() by
writing to the `hash` member of `struct object_id`, but that hash has
nothing to do with an object id (it's just a convenient location that
happens to be sized correctly).

Store the hash directly in an unsigned char array. This behaves the same
as writing to the `hash` member, but makes the intent clearer (and
avoids allocating an extra four bytes for the `algo` member of `struct
object_id`). It likewise prevents the possibility of a segfault when
reading `algo` (e.g., by calling `oid_to_hex()`) if it is uninitialized.
