[x265] [PATCH] testbench: Change error range in check_ssim_end4 from 0.0001 to 0.001

[Ramya Sriraman]

To correct an error spotted by our smoke tests on Darwin.For a particular
case where the seed is 56B3EFA7 in 12 bit build and for a one particular
input buffer, the primitive fails because the difference in the C and ASM
values is more than 0.0001. The ASM function uses the same algo as C.


Thank you
Regards
Ramya
