[PATCH v4 1/2] cat-file: extract printing batch error message into function

[Toon Claes <toon@xxxxxxxxx>]

There are two callsites that were formatting an error message in batch
mode if an object could not be found. We're about to make changes to
that and to avoid doing that twice, we extract this into a separate
function.
