Before, we required that the mount target exist and be a
directory for the 9p mount to successfully complete, which is not
how things are supposed to work - the user should be able to
mount anywhere. This should just be a simple mkdir, but with FCOS
the root directory is immutable so we need to undo that before we
can mkdir, and unfortunately we don't have a library that can do
chattr (and I didn't want to drag in a new dependency just for
that), so let's be gross and add it to the SSH command. I
aggressively dislike this but it does work.
[NO NEW TESTS NEEDED] Can worry about getting a more generic
mount test together for Machine later.

Moving from Go module v4 to v5 prepares us for public releases.
Move done using gomove [1] as with the v3 and v4 moves.

Logging to os.Stdout and os.Stderr does not seem to work in
Powershell. I am not entirely certain why.
Logfiles are the best alternative I can think of.

This includes two new hidden commands: a 9p server,
`podman machine server9p`, and a 9p client,
`podman machine client9p` with `server9p` currently only
configured to run on Windows and serve 9p via HyperV vsock, and
`client9p` only configured to run on Linux. The server is run by
`podman machine start` and has the same lifespan as gvproxy
(waits for the gvproxy PID to die before shutting down). The
client is run inside the VM, also by `podman machine start`, and
mounts uses kernel 9p mount code to complete the mount. It's
unfortunately not possible to use mount directly without the
wrapper; we need to set up the vsock and pass it to mount as an
FD.
In theory this can be generalized so that the server can run
anywhere and over almost any transport, but I haven't done this
here as I don't think we have a usecase other than HyperV right
now.
[NO NEW TESTS NEEDED] This requires changes to Podman in the VM,
so we need to wait until a build with this lands in FCOS to test.
