builtin/receive-pack: explicitly pass packfile fd

When processing the incoming packfile in git-receive-pack(1), `unpack()`
assumes it should always read it from stdin. In preparation for
`unpack()` logic being moved behind a generic ODB transaction interface,
update the function signature to take the an explicit fd provided by
callers to read the incoming packfile from instead. Call sites are
updated accordingly.
