Remove USE_PYTHON dependency for lang/python32, simplify build

[mva]

Summary

This removes the USE_PYTHON depdendency for lang/python32 to allow
bsd.python.mk to be transformed into a Uses file without any additional glue
code in Mk/

Additionally, the static/shared build has been replaced by the build process
used for lang/python34, which greatly simplifies the build.

PORTDATA and PORTEXAMPLES have been removed (for now).
