packfile.c: use checked arithmetic in `nth_packed_object_offset()`
In a similar spirit as the previous commits, ensure that we use
`st_add()` or `st_mult()` when computing values that may overflow the
32-bit unsigned limit.
Note that in each of these instances, we prevent 32-bit overflow
already since we have explicit casts to `size_t`.
So this code is OK as-is, but let's clarify it by using the `st_xyz()`
helpers to make it obvious that we are performing the relevant
computations using 64 bits.
