debian/changelog: Remove my name and reformat the version string

Silences lintian warning: native-package-with-dash-version

The reason I use debian format 3.0 (native) is because (quilt) needs upstream tarballs and for me it is hard to provide (because this repo is half of the upstream).

If you want to build alac yourself, plug your name and email to the appropriate fields in debian/changelog.
