intelmetool: Use correct type for pointer

Use `uintptr_t` instead of `uint32_t`, fixing the error below on 64-bit
systems, where pointers are 64-bit wide.

```
cc -O0 -g -Wall -W -Wno-unused-parameter -Wno-unused-but-set-variable -Wno-sign-compare -Wno-unused-function   -c -o intelmetool.o intelmetool.c
intelmetool.c: In function ‘dump_me_memory’:
intelmetool.c:85:45: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
  dump = map_physical_exact((off_t)me_clone, (void *)me_clone, 0x2000000);
                                             ^
```
