Jonathan Nobels 1191eb0e3d tstest/natlab: add unix address to writer for dgram mode
updates tailcale/corp#22371

For dgram mode, we need to store the write addresses of
the client socket(s) alongside the writer functions and
the write operation needs to use WriteToUnix.

Unix also has multiple clients writing to the same socket,
so the serve method is modified to handle packets from
multiple mac addresses.

Cleans up a bit of cruft from the initial tailmac tooling
commit.

Now all the macOS packets are belong to us.

tstest/tailmac: add customized macOS virtualization tooling (#13146)
updates tailcale/corp#22371

Adds custom macOS vm tooling.  See the README for
the general gist, but this will spin up VMs with unixgram
capable network interfaces listening to a named socket,
and with a virtio socket device for host-guest communication.

We can add other devices like consoles, serial, etc as needed.

The whole things is buildable with a single make command, and
everything is controllable via the command line using the TailMac
utility.

This should all be generally functional but takes a few shortcuts
with error handling and the like.  The virtio socket device support
has not been tested and may require some refinement.
