Both i.zc and r.surf.fractal depend of GRASS' gmath library functions with FFTW dependency.

(If it were direct dependency, adding FFTW to PRIMARY_DEPENDS would have been enough, but cannot be used as it also would link to FFTW.)

Closes #7446 and #7447.

Both tools depend of GRASS' gmath library functions with FFTW dependency.
