This patch does two things:
1. making user profiles preferred over system profiles
2. putting sub dirs of one profile to the right place
- before this patch, they are appended to the end of load-path
- after this patch, they are inserted right after the profile
Example value of load-path before this patch:

gobject-introspection is needed in nativeBuildInputs to fix
"error: Package <...> not found in specified Vala API directories
or GObject-Introspection GIR directories".
Upstream seems to publish and retain `.zip` more consistently than `.tar.gz`, which caused the previous expression to break. This modifies the odoo package and updater script to use the `zip` sources.
