scripts/decodecode: return 0 on success

The decodecode script always returns an exit code of 1, regardless of
whether the operation was successful or not.  This is because the
"cleanup" function, which is registered to run on any script exit via
"trap cleanup EXIT", contains an unconditional "exit 1".

Remove the "exit 1" from the "cleanup" function so that it only performs
the necessary file cleanup without forcing a non-zero exit status.

Do that to ensure successful script executions now exit with code 0.
Exits due to errors are all handled by the "die()" function and will still
correctly exit with code 1.
