graphics/partio: update the port to the latest version 1.19.2
Replace our SWIG interface patch with two ones from upstream:
- Add typemaps to ensure that the std::map parameters work
as expected
- Add overloaded methods to avoid ambiguous parameter errors
in newer versions of SWIG

graphics/partio: update the port to version 1.14.6 and enable tests
Three out of twelve test currently fail, two of them because they
import port's own Python bits which are not yet installed, and there
is no trick like LD_LIBRARY_PATH for C tests to the rescue.
