build: don't move pkg/lib/ to src/lib/

Keep pkg/lib in the same location as it is in the cockpit repository,
and adjust the include path accordingly.

This makes the production of the .pot file somewhat more deterministic:
previously, it would either include or not include the strings from
pkg/lib depending on if it had been checked out or not.  Now it never
includes them.

Cherry-picked from cockpit-podman commit a70630be2139a.
