[meta-oe] cmpi-bindings: allow creation of an empty package

From: Wang Mingyu <wangmy@fujitsu.com>

In the case where cmpi-bindings included into an image, and if no
layers is providing the machine configuration, the build fails with
the following error:
  Problem: conflicting requests
  - nothing provides lib32-cmpi-bindings

This error is because no package was created for cmpi-bindings
since the recipe does not install any files.

This commit allows the creation of an empty package in order to avoid
the do_rootfs failure when this package is included into an image.

what non-empty packages are built by this recipe.
I would rather expect them to be included in image install

Due to 3.13 incompatibility, python3 is disabled.
Because maybe upstream would update for Python3 in the future, I made this modification temporarily.
