Prefer stdckdint.h to intprops.h

Browse Source 
Problem reported by Collin Funk in:
https://lists.gnu.org/r/bug-tar/2024-07/msg00000.html
though this patch is more general than Collin’s suggestion.
* src/compare.c (diff_multivol):
* src/delete.c (move_archive):
* src/sparse.c (oldgnu_add_sparse, pax_decode_header):
* src/system.c (mtioseek):
Prefer ckd_add and ckd_mul to the intprops.h equivalents,
since stdckdint.h is now standard.
