Builds setuptools with both python2 & hostpython3crystax

Covers `setuptools` case in both `python2` and `hostpython3crystax`.
The `hostpython3crystax` build is supposed to fail until branch
`feature/ticket1154_hostpython3crystax_build_dir_and_synlink` is merged.
The merge will be done in next commit to demonstrate the fix.
Also adds android recipe case.
Plus removed the `uname -a` and `p4a apk --help` simple test cases since
the maximum of parallel run seems to be 5.
