devel/py-pyyaml: fix dependency on cython

pyyaml only builds with lang/cython and doesn't build with lang/cython3,
however USE_PYTHON=cython introduces a build-dependency on cython
executable which is installed by either cython version, thus the
dependency may be fulfilled by cython3 if it's installed, which is
incorrect and leads to a build failure. Fix this by switching to
explicit dependency on cython (and not cython3) package.

python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.
