Title: Remove gnuplot from package dependence (issue #735) and  Improve the test for Ubuntu by looking for /etc/debian_release file

Two minor fixes, we're dropping gnuplot from the package list dependence in frontend module.
On autotest server install script, I've changed the way we detect Ubuntu by looking for file ``/etc/debian_version``.
