reduce/improve library settings for paraview/vtk
More recent paraview versions do not an explicit LD_LIBRARY_PATH to run so this setting can be removed from the config.sh/ entry.
Verified with a fresh ParaView build/install under /tmp/make-thirdparty. Used these locations when building the PV-Plugins (aka, paraFoam modules). Relocated ParaView to the usual ThirdParty/platforms locations. Plugins load correctly.
Will need an additional mechanism to specify
libpaths for catalyst and runTimePostProcessing though.
