lavfi: avoid void* arithmetic in defaults.c:set_common_formats()

void* pointer arithmetic semantics is undefined, use uint8_t* instead.

Also fix GCC warnings:
defaults.c: In function ‘set_common_formats’:
defaults.c:184: warning: pointer of type ‘void *’ used in arithmetic
defaults.c:189: warning: pointer of type ‘void *’ used in arithmetic
