oeqa/runtime: Add testcases for kernel sample
We are going to let runtime test support kernel tests. Now we just add kernel self-contained sample tests. And we plan to add overall kernel tests in the future. This patch is just add kernel samples test which contains about 13 tests enabled by kernel-sample.scc. So it needs statement, KERNEL_FEATURES_append += " features/kernel-sample/kernel-sample.scc" in local.conf.
