Init files to setup a chroot-env so it run 3d applications

Run setupGraphicsEnv which will run the other F* init scripts
consecutively. The script needs the WORKSPACE path to be passed as the
first argument. The F-scripts do the following job:
* F02: Install apt-utils
* F03: Install TurboVNC debian package (i386 or amd64, according to
       chroot arch). The debian package needs to be located in
       $WORKSPACE/graphicTest/bin/. Add /opt/TurboVNC/bin to the
       PATH-Variable in ~/.bashrc after the installation succeeded.
* F04: Install VirtualGL. Same conditions apply as for F03.
Afterwards run the script $WORKSPACE/graphicTest/setupGraphicDriver.bash
which needs copied there by jenkins from the local machine. It's purpose
is to setup the graphic driver.
For the moment being run a test script (testGlx.bash ) afterwads to
check if everything is set up properly. testGlx starts a new vncserver
and glpxspheres64 (from /opt/VirtualGL/bin) for 10 seconds.
