alpha_processing_sse2: quiet signed conv warning

Browse Source 
After:
44f91b0d Speed DispatchAlpha_SSE2 up

_mm_set1_epi8 takes a char argument; add a `char` cast for 0xff.

from clang-14 integer sanitizer:
  implicit conversion from type 'int' of value 255 (32-bit, signed) to
  type 'char' changed the value to -1 (8-bit, signed)
