packfile: pass down repository to for_each_packed_object

The function `for_each_packed_object` currently relies on the global
variable `the_repository`. To eliminate global variable usage in
`packfile.c`, we should progressively shift the dependency on
the_repository to higher layers. Let's remove its usage from this
function and closely related function `is_promisor_object`.
