[oe] [meta-oe] [PATCH] fftwf and fftwl: exclude them from world

[Robert Yang]

The fftw, fftwf and fftwl provide the same files (different contents), we
should only build one of them, otherwise there would be warning

WARNING: The recipe fftw is trying to install files into a shared area when those files already exist. Those files and their manifest location are:
   sysroots/qemux86-64/usr/include/fftw3.f03
   Matched in manifest-qemux86-64-fftwl.populate_sysroot
manifest-qemux86-64-fftwf.populate_sysroot
   sysroots/qemux86-64/usr/include/fftw3.h
   Matched in manifest-qemux86-64-fftwl.populate_sysroot
manifest-qemux86-64-fftwf.populate_sysroot
   sysroots/qemux86-64/usr/include/fftw3q.f03
   Matched in manifest-qemux86-64-fftwl.populate_sysroot
manifest-qemux86-64-fftwf.populate_sysroot
   sysroots/qemux86-64/usr/include/fftw3.f
   Matched in manifest-qemux86-64-fftwl.populate_sysroot
manifest-qemux86-64-fftwf.populate_sysroot
   sysroots/qemux86-64/usr/include/fftw3l.f03
   Matched in manifest-qemux86-64-fftwl.populate_sysroot
manifest-qemux86-64-fftwf.populate_sysroot
Please verify which package should provide the above files.

and maybe errors (race issue):

The recipe imagemagick.do_compiler error:
  fourier.c:69:19: fatal error: fftw3.h: No such file or directory
   #include <fftw3.h>

This is because imagemagick.do_configure depends on fftw.populate_sysroot, but
the files installed by fftw.populate_sysroot, maybe removed by fftwl or fftwf
when they rebuild.

Only build fftw in the world will fix the problem.
