swscale: prevent undefined behaviour in the PUTRGBA macro
For even small values of 'asrc[x]', shifting them by 24 bits or more
will cause arithmetic overflow and be caught by
GCC's undefined behaviour sanitizer.

Ensure the values do not overflow by up-casting the bracketed
expressions involving 'asrc' to uint32_t.
