    devel/py-setuptools_scm: Do not run "git archive" on Ports tree

    * In build environments have git installed in conjunction with a
      git-based Ports tree and haven't WRKDIRPREFIX set, there will be
      significant delays when building devel/py-setuptools_scm or ports
      that depend on it.

      This is because the top-level directory of the git repository is
      determined during build via "git rev-parse --show-toplevel" which is
      issued inside the WRKSRC directory.

      Once the top-level directory (which is PORTSDIR) has been determined,
      an archive is created from this point using "git archive" which is
      then very time-consuming due the complexity of the Ports tree.

      In environments (e.g. poudriere) that have WRKDIRPREFIX set and also
      have git present during build, the issue doesn't appear because
      "git rev-parse --show-toplevel" fails silently with "not a git repo".

      Remedy the issue by returning only the actual path of WRKSRC, but only
      if it has "setup.py" in it (= devel/py-setuptools_scm is built) or a
      test session is performed.

    * Modernize the "do-test" target while I'm here and bump PORTREVISION
      due package change.
