Cinemasci server not working with 5.9.0-RC4

@utkarsh.ayachit @dhr is aware and working on a fix. If this can still make it into 5.9.0, that would be great. Thanks.

Steps to reproduce:

1. Download and install 5.9.0-RC4 from paraview.org
2. Run the cinemasci server (no cinema database needed to reproduce) with /Applications/ParaView-5.9.0-RC4.app/Contents/bin/pvpython -m paraview.tpl.cinemasci.server

Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
