tests: move "venv" to "build-root" directory from "test" directory

Type: refactor

- refactored VPP test code to remove "ignore_path" variable
  from "discover_tests" function and "run_test" code
- configured VPP test makefile, config file, and 'run.sh' shell script
  to move "venv" directory from "test" dir to "build-root" dir
