Reduce APK size by omitting unnecessary files and duplications

- include the 'quiet' flag to compileall to reduce noise
- fix bug in non-zip packaging to not include files in the ZIP bundle
- switch to more flexible and enlargeable definition of files to not bundle in ZIP and at all
- don't bundle distutils, compiler and other Python libs that are big and unnecessary

(these changes - apart from the "quiet" flag of course - reduced my APK from 8MB to 6MB)
