kunit update for Linux 6.13-rc1
-- fixes user-after-free (UAF) bug in kunit_init_suite()
-- adds option to kunit tool to print just the summary of test results
-- adds option to kunit tool to print just the failed test results
-- fixes kunit_zalloc_skb() to use user passed in gfp value instead of
hardcoding GFP_KERNEL
-- fixes kunit_zalloc_skb() kernel doc to include allocation flags variable
-- updates KUnit email address for Brendan Higgins
-- adds LoongArch config to qemu_configs
-- changes tool to allow overriding the shutdown mode from qemu config
-- enables shutdown in loongarch qemu_config
-- fixes potential null dereference in kunit_device_driver_test()
-- fixes debugfs to use IS_ERR() for alloc_string_stream() error check
diff is attached.
