[pbs-devel] [PATCH v2 proxmox-backup 4/5] cargo: add stubs for `ipconfig` windows build dependency

[Christian Ebner]

`hickeroy-resolver` depends on ipconfig for name resolution on
Windows. Eventhough the build is not configured for windows and the
dependency should be disabled, cargo nevertheless expects the
dependency to be found in the registry.

As a workaround, add a dummy crate and point the registry to it,
in order to build without having to pull in the actually unused
dependency.

In preparation for adding `hickeroy-resolver` as alternative to
`getaddrinfo` based name resolution to be used for the statically
linked proxmox-backup-client.
