[PATCH] kunit: tool: Import missing importlib.abc

[Michał Winiarski]

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.
