Fix stat for 32-biut linuxes

- Reenable fix to ensure that stat works correctly on 32-bit linuxes again
  - stat will return 32-bit inodes when checking a file. So when this call will be used on a 64-bit linux this will cause errors like:
Error writing to foo: Value too large for defined data type
File I/O error: foo
- closes https://github.com/assimp/assimp/issues/4390
