Update setuptools version

[oshino-shinobu]

Master branch of Kivy fails to compile with current version of setuptools:
ImportError: project/.buildozer/android/platform/python-for-android/build/python-install/lib/python2.7/lib-dynload/_io.so: wrong ELF class: ELFCLASS32

Setting setuptools version to 1.2 in its recipe solved the problem for me.

kivy-stable, Ubuntu 14.04 64bit
setting version of setuptools didn't work, error was the same

This kind of issues appears here and there regularly...
Is there a possibility to write a "standard" guide to solve this?

I've just got the same issues after adding plyer to buildozer.spec.

@ecdsa had the same issue for him installing cython using apt-get instead of pip helped fix this.

I haven't seen this come up for a while, and the new toolchain should certainly resolve it anyway, so I'll close this.
