Subject: [PATCH] Packages: add sshfs

This allows the guest to mount any host directory "out of the box" with
zero qemu or kernel feature to enable.  Thanks to `dpipe` and "reverse
sshfs", this does not require any additional ssh configuration either:

https://blog.dhampir.no/content/reverse-sshfs-mounts-fs-push
```
dpipe /usr/lib/openssh/sftp-server = ssh CLIENT sshfs :/mnt/host/path /mnt/client/path -o slave
```

This Just Works out of the box.

Just for the record, virtiofs and 9P are the most popular and likely
much faster alternatives but sshfs is "good enough" in most
cases. virtiofs seems to clash with what we already do ("NUMA distance
missing" error, etc.) and 9P is rumoured to be quite slow too.

Also add "ping" and friends on Arch Linux.
