Rémi Denis-Courmont 58ac1f9ea8 lavc/sbrdsp: fix potential overflow in noise table
Since the SBR noise application optimisations are currently restricted
to hardware with 128-bit vectors, and use a quadruple multipler, they
can load up to 16 32-bit elements. But the "loads" are of 2 segments,
or 16 pairs of single precision float.

Thus we need to expand the dupiclated section of the noise table from
2x8 to 2x16 to avoid overflows.
