[bug#54539] [PATCH 1/6] gnu: audacity: Move into new module to break cycles.

[Maxime Devos <maximedevos@telenet.be>]

Currently, there's a cycle between ncurses, linux, audio and music.
By moving audacity to its own module, 'audio' does not have to import
'music' and 'linux' anymore.  Looking at the output of
"guix graph --type=module", there still appears to be cycles, so
this commit will not sufficient by itself.

* gnu/packages/audio.scm (audacity): Move to ...
* gnu/packages/audacity.scm: This new module.  Remove unneeded imports
  from the old module.  Add a few comments to the old module to discourage
  re-importing the 'linux' and 'music' module in the future.
* gnu/local.mk (GNU_SYSTEM_MODULES): Register new module.
