Edit Package fftw3

FFTW is a C subroutine library for computing the Discrete Fourier
Transform (DFT) in one or more dimensions, of both real and complex
data, and of arbitrary input size.

This SR satisfies jsc#SLE-16462 & jsc#SLE-14839.

- Add build support for gcc10 to HPC build (bsc#1174439). 

- update to 3.3.9:
  * New API fftw_planner_nthreads() returns the number of threads
    currently being used by the planner.
  * Fix incorrect math in 128-bit generic SIMD
  * Fix wisdom for avx512.
    The avx512 alignment requirement was set to 64 bytes, but this is
    wrong.  Alignment requirements are a property of the platform (e.g.,
    x86) and not of the instruction set (e.g., AVX).  Among other
    things, this broke wisdom with avx512.
    Note that avx512 support is still experimental because the FFTW
    authors have no avx512 hardware available for testing.
  * fftw_threads_set_callback function to change the threading backend at runtime.

- Remove specific mpi_implemen define for ppc/ppc64 (was openmpi)
  to use same openmpi2 as other architectures.
