[vtkusers] Can't compile 5.2.1, CVS. *fixed* Bug in Cmake scripts with 64bit systems

[Paul]

Fixed the problem. Turns out it's an issue related to 64bit systems.

In the CMake scripts, it is incorrectly determining that my system doesn't
support "long long"'s for istream/ostream. Despite this, it would still use
long long's as vtkIdType. (This should generate a warning)

Thus VTK would try to build without a compiler flag enabling long long
support, thereby generating errors anywhere a vtkIdType (long long) is fed
to istream/ostream.
