compilation fixes for check_ntp.c:

- check_ntp.c:290: warning: overflow in implicit constant conversion
  fixed with an explicit cast to int8_t.
- check_ntp.c:544: warning: pointer of type ‘void *’ used in arithmetic
  fixed by casting to ptrdiff_t before arithmetic and (void*) afterwards
- in TVtoNTP64, cast arithmetic result passed to R32 as uint64_t.
