lib/{ext2fs,support}: fix 32-bit Windows build

_WIN32 is the standard macro to detect (native) Windows, regardless of
32-bit or 64-bit.  _WIN64 is for 64-bit Windows only.  Use _WIN32 where
_WIN64 was incorrectly being used.

This fixes several 32-bit Windows build errors, for example this one:

plausible.c: In function ‘print_ext2_info’:
plausible.c:109:31: error: ‘unix_io_manager’ undeclared (first use in this function); did you mean ‘undo_io_manager’?
  109 |                               unix_io_manager,
      |                               ^~~~~~~~~~~~~~~
      |                               undo_io_manager
