systemctl: do print all statuses/signals received from pid1

If for some reason we do not know some signal, instead of silently
skipping it, let's print it numerically. Likewise, 'show' is not the
right place to do value filtering for exit codes. If pid1 accepted it,
let's just print it with no fuss.
