Switch to official vtk 7 available in hombrew/science about homebrew-freecad HOT 5 CLOSED

It looks like there is progress by the vtk team that may make this possible. See:

Homebrew #3811 has been merged that includes VTK: fix linking to python

from homebrew-freecad.

The upstream fix still doesn't resolve the "segmentation fault" we get almost immediately upon launch when using hombrew/science/vtk that defaults to --with-python but purportedly fixed so there are no longer references to the system python...

*** Abort *** an exception was raised, but no catch was found.

This will have to stay on the list a bit longer...

The root cause for the crash was due to incorrectly configured dynamic loader paths that resulted in loading binaries external to the bundle. PR 535 resolves the path issues that prevented us from using the production VTK with python bindings.

PR FreeCAD/FreeCAD#554 is also required and was just merged by Yorik. All green for moving to standard Homebrew VTK install.

Re-generating the ports-cache to cache the Homebrew vtk port to fully resolve this issue.
