    checkasm: ac3dsp: Increase the float tolerance for sum_square_butterfly_float
    
    Accept up to 13 ULP difference.
    
    This fixes running "checkasm --test=ac3dsp 3044836819" on ARM.
    
    Depending on how the SIMD implementations aggregate numbers,
    larger/smaller values might not end up accumulated in exactly
    the same way; the current NEON implementation for ARM aggregates
    into vectors of 2 elements. If it would aggregate into vectors
    of 4 elements instead, like the AArch64 version does, this particular
    case would end up with a smaller difference.
