fft-eval: update to the version with ath11k support

Latest fft-eval has some extra features such as ath11k support, double precision in json signal calculation, and cleanups (batctl references, minor bugfixes, etc )
This commit is a version and makefile update. Now the native project Makefile do the job (compilation and linking).
