Now that it's fixed, we can use it instead of a custom call into internal KUnit functions to run the test. As a side-effect, this means that the test results are properly included with other suites when built-in. To celebrate, enable the test by default when KUNIT_ALL_TESTS is set (and NITRO_ENCLAVES enabled). The nitro_enclave tests can now be run via kunit_tool with: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_SMP=y \ --kconfig_add CONFIG_HOTPLUG_CPU=y \ --kconfig_add CONFIG_VIRT_DRIVERS=y \ --kconfig_add CONFIG_NITRO_ENCLAVES=y \ 'ne_misc_dev_test' (This is a pretty long command, so it may be worth adding a .kunitconfig file at some point, instead.)
