[Buildroot] [v2 1/2] caps: new package

[Martin Bark]

CAPS is a collection of audio plugins comprising virtual guitar
amplification and a small range of basic classic effects, signal
processors and generators of often elementary and occasionally
exotic nature.

The plugins aim to satisfy the highest demands in sound quality
with maximal computational efficiency and zero latency.
