initfs: shutdown: comment on update success
Print an error from the shutdown script when the update fails.
Update is changing to return codes when its preconditions are not
met, so be more verbose about its success to provide a means to
debug flash updates not occurring.
We could add a sulogin or sushell but its not clear what would be
desired here. If so the message should include "rmdir /oldroot
to get a PID 1 shell" like /takever works in init.
