Let supervisor buffer last 4KB of program output in case laitos panics

It is often quite inconvenient to investigate a laitos panic right away, but then its log file can be gone in a day or two. Therefore, tell supervisor to buffer the latest ~4KB of program output, and send it via the recovery notification email.
