[PATCH 01/14] qapi: Fix error message format regression

[Markus Armbruster <armbru@redhat.com>]

Commit 52a474180ae3 changed reporting of errors connected to a source
location without mentioning it in the commit message.  For instance,

    $ python scripts/qapi-gen.py tests/qapi-schema/unknown-escape.json
    tests/qapi-schema/unknown-escape.json:3:21: unknown escape \x

became

    scripts/qapi-gen.py: tests/qapi-schema/unknown-escape.json:3:21: unknown escape \x

This is not how compilers report such errors, and Emacs doesn't
recognize the format.  Revert this change.

Fixes: 52a474180ae3 (qapi-gen: Separate arg-parsing from generation)
