fft-eval: add package

This program has been created to aid open source spectrum analyzer
development for Qualcomm/Atheros AR92xx and AR93xx based chipsets.

Find more information about the package here:
https://github.com/simonwunderlich/FFT_eval

This package is used in LibreMesh, however our CI doesn't support
multiple architecures as all LibreMesh code is lua. Adding this package
to the official repos allows us to offer it in our tool chain.
