python3: fix run-time deps for core python3 libraries
The http.server module from python3-netclient imports the html module
which is in python3-html. Also xmlrpc.server imports pydoc which is a
part of python3-pydoc. But those run-time dependencies are missing
from python3-netclient and python3-xmlrpc respectively.
Add the missing run-time dependencies.
