[vtkusers] Improvements for VTK makefiles.

[David Gobbi]

Hi Prabhu,

This is just to confirm that I committed the python-related changes and
they work fine.  Also, the RPMs now install in /usr (not /usr/local),
you mentioned that you'd like to see this (thanks, Dan).

As for the java & install changes, I won't have time to look at them
anytime soon but if someone else with CVS write access could take a
peek, please do!
