builtin/receive-pack: pass shallow file explicitly

If shallow information is provided during `unpack()`, a temporary
shallow file is created and stored in global state. In a subsequent
commit, the `unpack()` logic is moved behind a generic ODB transaction
interface to handle writing packfiles and thus can no longer rely on
such global state. Lift the setup of the temporary shallow file out of
`unpack()` and wire it through to its call sites explicitly.
