[PATCH] D84511: Fix update_cc_test_checks.py --llvm-bin after D78478

Not passing --clang would result in a python exception after this change:
(TypeError: expected str, bytes or os.PathLike object, not NoneType)
because the --clang argument default was only being populated in the
initial argument parsing pass but not later on.
Fix this by adding an argparse callback to set the default values.
