Python 3.10.0 contains:
9e09849d20 ("bpo-41006: importlib.util no longer imports typing (GH-20938)")

It causes importlib.util to no longer import importlib.abs, which leads
to the following error when trying to use kunit with qemu:
AttributeError: module 'importlib' has no attribute 'abc'. Did you mean: '_abc'?

Add the missing import.

Thanks for catching this! I completely forgot to add the import.

For context to others, the relevant line is
216          assert isinstance(spec.loader, importlib.abc.Loader)
which was added by me in commit 52a5d80a2225 ("kunit: tool: fix
typecheck errors about loading qemu configs").

We could potentially add a Fixes: tag on this, but this looks good to me.
