opencv.spec.patch

rm -rf 3rdparty/ breaks the build of 3.3.0 , that is why I had submit it , to let you review first .

Also got a patch for opencl-headers which let build Eigen in ppc64le [2]

Be careful with 3dparty folder, due some of libraries don't have to meet license criteria for Fedora distribution or license of opencv package would have to be modified. 

I suggest to upgrade opencv package for fedora 27+ only.

opencv.spec.v2.patch

OK , could manage the way to remove 3rdparty/ ... 
may I commit this patch for F28 ?

Add to this rebase even fix for bz#1487816 (in case its not applied already) and keep directory remove command with force option.

OK, upstream closed my issue [1] and seems all security fixes are available in 3.3.1, I'm ready to begin build on rawhide.
