importlib_resources: drop outdated and unused recipe. (#11936)

Not required on-tree since dc675a224a.

`setuptools` uses a vendored version of this now, so we should not
require this stand-alone package any longer.

Users should try to `pip install` this, if they need it.

-SUMMARY="A backport of Python standard library importlib.resources"
-DESCRIPTION="The key goal of this module is to replace parts of pkg_resources \
-with a solution in Python's stdlib that relies on well-defined APIs.  This makes \
-reading resources included in packages easier, with more stable and \
-consistent semantics."
