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.
