turn banner (printed before auth) into MOTD (printed after login)
...
This means the message will be printed only once when using the breakglass
command line tool (which first copies over a tarball, then logs in).
Also switch to fancy ASCII art while we’re at it :)

use renameio to avoid “text file busy” errors
...
Before this commit, extracting a breakglass would fail when /tmp/breakglass*/sh
was busy because it was being run in a separate connection.

breakglass command: add -proxy flag for easier ProxyCommand usage

Now you can use the following in your ~/.ssh/config for example:
Host scan2drive-backup
Hostname scan2drive.lan
IdentityFile ~/.ssh/id_ed25519_scan2drivebackup
ProxyCommand breakglass -proxy scan2drive.lan

recommend ed25519 host keys
...
Newer OpenSSH versions seem to have problems with (some?) older ssh-rsa keys,
so I figured we could switch to ed25519 and avoid any confusion regarding
ssh-rsa support.

The special syntax :1080 means “use the default, but force port to 1080”,
which is useful when you are running the gokrazy web interface on a different
port because you need port 80 for your web appliance.
