avfilter/vf_ssim360: Use correct type in sizeof

SSIM360Context.ssim360_hist is an array of four pointers to double;
so sizeof(*ssim360_hist[0]) (=sizeof(double)) is the correct size
to use to calculate the amount of memory to allocate, not
sizeof(*ssim360_hist) (which is sizeof(double*)).

Use FF_ALLOCZ_TYPED_ARRAY to avoid this issue altogether.

Fixes Coverity issue #1520671.
