net/py-sbws: update 1.1.0 to 1.3.0

    - python:3.5+ now became python:3.6+;
    - move away from USE_GITHUB, and use USE_GITLAB instead;
      -- Tor Project has its official GitLab instance;
      -- GL_SITE set to follow 'gitlab.torproject.org/tpo';
    - fixed RUN_DEPENDS to reflect updated version of sbws;
    - add TEST_DEPENDS dependencies to test source;
      -- do-test stage added accordingly;
    - apply 'shebangfix' to .sh scripts which need bash;
    - update LICENSE_FILE;
    - make sure we include a @sample config file now (sbws.ini).
