changed swap file numbers in `map.cc` to uintptr

  We know swap file numbers are limited to the [1, 99999999] range
which fits a uint32, but using anything but uintptr requires us to
do extra casts to avoid compiler warnings so we only convert back
to uint32 when building the swap file name which should work the
same.
