[PATCH 3/3] list-objects-filter: give a more specific error sparse parsing error

[Jeff King <peff@peff.net>]

From: Jon Simons <jon@jonsimons.org>

The sparse:oid filter has two error modes: we might fail to resolve the
name to an OID, or we might fail to parse the contents of that OID. In
the latter case, let's give a less generic error message, and mention
the OID we did find.

While we're here, let's also mark both messages as translatable.
