sci-libs/rocFFT: add 5.1.3, use rocm.eclass

profiles/base: mask rocFFT-5.1.3 gfx906 amdgpu target, because
intolerable error found on Radeon VII.

No need to rebuilt rocFFT when hip upgrade because librocfft is
dynamically linked to libhipamd, while llvm SLOT does not matter because
it is only used to produce GPU kernels, libclang and libLLVM does not
linked in.
