This is in essence fixes pip3.

That means pip3 will ship without Python byte-codes
for a while, until I'll find a better way to fix it.

I couldn't think of a not-very hack-ish way of doing it.

The only draw-back of this, will be that pip3 will run
a bit slower ; but that should be ok for a while.

python3-pip & python3-setuptools have slightly
different installation mechanisms.

We need to remove the __pycache__ folders.
Seems they're generated.

This also reduces the size of the python3-pip &
python3-setuptools packages.

Python packages try to enforce their own.
For some cases this may not be desired.

I admit this may be be a bit aggressive, but the lang
folder is getting cluttered/filled up with Python, PHP, Perl,
Ruby, etc. packages.

Makes sense to try to group them into per-lang folders.

I took the Pythons.
