[GNU-linux-libre] NONFSDG: Audacity, Free Abuse extensions

[Sam Geeraerts]

Two more entries for the NONFSDG list, with thanks to Jason Self.

* Audacity: one file in the Nyquist plugin has a non-commercial clause [1].
* Free Abuse extensions: the "Claudio" add-ons don't allow distribution 
and only non-commercial use [2].

I'll add them to the list if there are no objections.
