gnu: Add audiofile.
Patches should fix all CVEs reported by `guix lint`:
CVE-2015-7747; CVE-2017-6827, CVE-2017-6828, CVE-2017-6829,
CVE-2017-6830, CVE-2017-6831, CVE-2017-6832, CVE-2017-6833,
CVE-2017-6834, CVE-2017-6835, CVE-2017-6836, CVE-2017-6837,
CVE-2017-6838, CVE-2017-6839; CVE-2018-13440; CVE-2018-17095
Since the patches do not reference to CVEs, it's a bit hard to tell which
patch actually closes which CVE. Debian reports all these to be closed by
the patches below and NixPkgs provides references.
