[OE-core] adding python modules

[Burton, Ross]

If you're referring to the standard library modules then they should
be installed for you as when you say to install python3, you actually
get python3-modules.

If you want to install further non-standard modules then just add them
to the image, for example python3-pip will give you pip.
