jaxlib 0.3.0 conda-forge package is broken

[hawkinsp]

A user reports that the conda-forge jaxlib package is currently broken:

google/jax#9643

The official pip packages don't seem to have this problem, so it must be something specific to the conda-forge build.

I strongly suspect that using a dynamically linked protobuf is responsible. jaxlib quite intentionally does not share its protobuf libraries between even its own extensions: multiple extensions (and for that matter, other packages like tensorflow) contain some of the same protocol buffer definitions. If you dynamically link, this will break.
