crypto: x86/aria-avx2 - fix build failure with old binutils
The minimum version of binutils for kernel build is currently 2.23 and
it doesn't support GFNI.
So, it fails to build the aria-avx2 if the old binutils is used.
The code using GFNI is an optional part of aria-avx2.
So, it disables GFNI part in it when the old binutils is used.
Fixes: 37d8d3ae7a58 ("crypto: x86/aria - implement aria-avx2")
