lib/hexdump: Use `size_t` for length parameter of `hexdump32()`

In the signature of the function `hexdump32()` it does not make sense to
represent a length, assumed to be positive, as a signed integer.
With this change, it is no longer necessary to cast a pointer to
unsigned long when passing it to `hexdump32()`.

The same change for the function `hexdump()` was done in commit
3dd0e72d [1].
