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 += " kernel-sample/kernel-sample.scc" in
local.conf.

kernel-sample feature has been merged into master branch.
