Robbie Harwood b8b072ddcd loader/emu/linux: Work around systemctl kexec returning ...

Per systemctl(1), it "is asynchronous; it will return after the reboot
operation is enqueued, without waiting for it to complete". This differs
from kexec(8), which calls reboot(2) and therefore does not return.

When not using fallback, this confusingly results in:

  error trying to perform 'systemctl kexec': 0
  Aborted. Press any key to exit.

on screen for a bit, followed by successful kexec.

To reduce the likelihood of hitting this case, add a delay on successful
return. Ultimately, the systemd interface is racy: we can't avoid it
entirely unless we never fallback on success.
