hyperv-daemons: Install the sample network info scripts

Currently hv_kvp_daemon can report the interface address configuration
to the hypervisor, but not whether DHCPv4 is enabled on an interface
or what DNS servers are being used.

It tries to run external scripts to find this out, but we didn't
install any.  This was partly because the sample DHCP information
script was useless on Debian systems and no-one contributed a suitable
implementation.

Now that the DHCP information script should generally work, install
both the sample scripts.

We are still missing an hv_set_ifconfig script which will be called to
apply network configuration changes from the hypervisor.

Closes: #919350
