package/python-bluezero: add recursive dependencies

python-bluezero selects python-gobject but fails to include its arch and
toolchain dependencies. Add them now, as well as the corresponding
comment.

dbus-python also has some dependencies, but all of them are covered by
the python3 dependency, so don't bother with those.

Fixes: 8bdc5e7c4d975193b1e18999ed840507cea63bd6
