graphics/py-graphviz: Move to py-pygraphviz, Fix 3.x build

There are numerous graphviz related packages in PyPI, including:
graphviz, graphviz-python and pygraphviz.

This port, py-graphviz, is not and does not provide the same package
as the 'graphviz' package on PyPI (CHEESESHOP).

Further, it blocks the creation of a correctly named py-graphviz port,
is a POLA violation in terms of users expecting to find and recieve
the package they expect based on a standard search, and is likely to
create confusion among other ports if they depend on a python graphviz
package, which could result in incorrect packages/dependencies.

This is why among other reasons, Python packages should be named
exactly what they are called in PyPI, or inside install_requires,
setup_requires or tests_requires as dependencies in other packages.

This change moves py-graphviz to py-pygraphviz to correct the above
incorrect naming.

While I'm here:

- Remove backup (http) MASTER_SITES, CHEESESHOP is highly-available
  and provides a Geo-aware CDN by Fastly.
- Remove {BUILD,RUN}_DEPENDS in favour of the actual LIB_DEPENDS
- Use PYDISTUTILS_* framework variables to customise the build instead
  of hack patching setup.py
- Enable autoplist, fixing builds on Python 3.x [1]
- Enable concurrent (Python version) installation
  - Hack patch setup.py to preclude docs installation, as it adds a
    directory to --record and breaks pkg-plist output [2]
- Remove DOCSDIR override (no longer necessary)
- Assign MAINTAINER'ship to python@
- Add TEST_DEPENDS and test target
- pkg-descr: Match WWW URL to setup.py:homepage field
- pkg-descr: Improve package description text (matching upstream)

While I'm sweeping dependencies:

- Fix a typo in science/gramps: s|>-|>=
