swscale/output: Fix integer overflow in yuv2rgba64_1_c_template ...

Fixes: signed integer overflow: -831176 * 9539 cannot be represented in type 'int'
Fixes: 67869/clusterfuzz-testcase-minimized-ffmpeg_SWS_fuzzer-5117342091640832

The input is 9bit in 16bit, the fuzzer fills all 16bit thus generating "invalid" input
No overflow should happen with valid input.
