Subject: [OE-core] [meta][PATCH 2/2] Meta runtime cases: 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.
