[Paraview] pvbatch is not working with newer osmesa releases

[burlen]

some more info

* running the script using pvpython and a separate invocation of 
pvserver works correctly with any number of mpi ranks
* running pvbatch with 1 mpi rank produces visually correct result (but 
valgrind still reports over 1000 errors)
* I compared the ldd output from pvserver and pvbatch they're line for 
line identical (was thinking that maybe this could be a factory issue)

I simplified the test script further and added the code to connect to 
pvserver with pvpython. attached.

over the weekend I updated the hopper.nersc.gov dashboard to build 
against ver 9.2.0 mesa from git, and most of the failures are because of 
this issue.
