python-cython: Add new host-only package

The host build replaces the use of the host pip requirements file. This
also updates the dependants of Cython to depend on the host build.

+Cython is a language that makes writing C extensions for Python as easy
+as Python itself. Cython is based on Pyrex, but supports more cutting
+edge functionality and optimizations.
+
+The Cython language is very close to the Python language, but Cython
+additionally supports calling C functions and declaring C types on
+variables and class attributes. This allows the compiler to generate
+very efficient C code from Cython code.
+
+This makes Cython the ideal language for wrapping external C libraries,
+and for fast C modules that speed up the execution of Python code.
