initfs: update: Don't exec sh or sulogin on error just exit 1

When update was written it was exec'd from the shutdown script
and hence took over pid 1.  Since exiting in that environment was
a panic situation, the script instead started a rescue shell with
its output presumably on the console.

The calling convention was updated to be a simple invocation in
commit dbacf104885c ("obmc-initfs: run update as a sub-script")
but the error handling was not updated.  That error handling is
now becoming a hindrance to use from additional environments so
change it.
