[CMake] Remove all rpaths on install

[Orion Poplawski]

We need to make sure that all rpaths are removed on install when 
building Fedora rpms.  How can we achieve this?  We still see /usr/lib64 
being added (twice!) to items:


  0x000000000000000f (RPATH)              Library rpath: 
[/usr/lib64:/usr/lib64]

Get "/usr/lib:/usr/lib" on 32-bit machines.

This is with cmake 2.6.3 RC 13

-DINSTALL_RPATH="" (or -DCMAKE_INSTALL_RPATH="" which should it be?) 
seems to have no effect.
