openvswitch: drop no longer existing python3 dependencies
openvswitch: drop no longer existing python3 dependencies

Several python3 packages have been removed as the functionality has
been moved into python3 core. As such we can no longer RDEPENDS on
these packages, nor is there a need to.

See similar commits in meta-openembedded:
df997e0747de - Remove deprecated python3-subprocess from the RDEPENDS
90b1f996af78 - Remove deprecated python3-argparse from the RDEPENDS
ef52e9980433 - Remove deprecated python3-lang from the RDEPENDS

This is fallout from openembedded core commit:
54ac820b8a63 - python3: Restructure python3 packaging and replace it
               with autopackaging
