repack-promisor: allow excluding objects from the rebuilt promisor pack 

Add a to_drop oidset parameter to repack_promisor_objects(). When it is
non-NULL, write_oid() omits those objects from the rebuilt promisor
pack. This is the mechanism --drop-filtered will use to remove promisor
blobs, i.e. rebuild the promisor pack without them.

All existing callers pass NULL, so behavior is unchanged.
