conv_acc: Our code requires SSSE3, not just SSE3
The accelerated convolutional decoder uses SSSE3 instructions such as PSIGNW (via _mm_sign_epi16) which go beyond what SSE3 offers. So let's make sure we use the right compiler flag (-mssse3) and also the right runtime check. Without this patch, we would use illegal instructions e.g. on Opteron Gen3 such as Opteron 2427, which are also used as build.opensuse.org build hosts (build31 through build36) where we wouldn't pass "make check" as a result.
