gnu: supercollider: Enable SCClassLibrary library lookup.

This hardcodes the path of SCClassLibrary to fix a lookup error that was
preventing SCServer's boot.

* gnu/packages/audio.scm (supercollider)[source]: Fetch via git,
[arguments]: build release target and add a new 'patch-scclass-dir phase to
hardcode SCClassLibrary path.
