msgmerge: output as source when --update is passed

following https://github.com/sabotage-linux/gettext-tiny/issues/14,
because there're programs using msgmerge --update, abort may break the
build.

As our goal is not to provide these utils of translators, we assume
that nobody would actually make use of these utils. We just provide a
stub to pass the build safely.
