paths: Modify algorithm for PATHS verification
VSPERF verifies if PATHS to the tools (vSwitch, VNF, etc.) are valid. This check was modified to take into the account tools required by selected testcase. It will help to avoid runtime errors triggered by missing tools, which are not essential for testcase execution.
