[oe] [meta-python][master][pyro][PATCH] python-cython: mangle scripts to use /usr/bin/env python

[S. Lockwood-Childs]

This prevents runtime failure "bad interpreter: No such file or directory"
from running native cython when the native python is installed
at a long path, exceeding the 128-character limit for shebang lines
on linux. Exceeding the limit was already possible when using a long
path for topdir, but it got easier to exceed after the switch to per-recipe
sysroots.
