The two libraries' (readline and gdbm) licenses belong to the GPLv3
family. Add them to to PACKAGECONFIG so they can be switched off if the
licensing doesn't allow using them. Python build system autodetects the
dependencies but doesn't allow them to be explicitly disabled, so just
deal with the dependencies.

The defaults in PACKAGECONFIG are the same as before, so there should be
no change to current users.
