[PATCH] Pass --ipv4 and --ipv6 options to sub-fetches when fetching multiple remotes and submodules

The options indicate user intent for the whole fetch operation, and
ignoring them in sub-fetches is quite unexpected when, for instance,
it is intended to limit all of the communication to a specific transport
protocol for some reason.
