devel/py-pygit2: Fix RUN_DEPENDS

- cached-property is only required for Python 3.7 and below
- six is not required
- Update version requirement of *_DEPENDS
- Bump PORTREVISION for dependency change

from setup.py:
install_requires = ['cffi>=1.4.0']
if sys.version_info < (3, 8):
    install_requires.append('cached-property')
...
    setup_requires=['cffi>=1.4.0'],

from CHANGELOG.rst:
- Don't require cached-property with Python 3.8 or later
...
- Drop Python 2.7 and 3.4 support, six no longer required
