support/testing: remove leftover kernel config fragment
Commit 86d32208b62a (support/testing/tests/init/test_systemd.py: use
downloaded kernel) stopped building a custom kernel for the systemd
tests, but forgot to drop the associated kernel config fragment.
That fragment is now not used in any test case, so we can drop it.
