Wrapper for running tests in osci
    
    run/osci/runtest.sh - runs tests defined in <os-version>.tests file
                          and reports results
    run/osci/setenv.sh  - sets the environment - install all needed packages,
                          create user test and set gdm
    run/osci/<os-version>.tests - files with tests to run for given <os-version>
    
    Also I amended runtest.sh to terminate session for user test after test run
    ends.
