kernel-selftest: Add a recipe on kernel selftest

The recipe builds the framework for kernel-selftest. Now, it just
contains two sets of testcase, bpf and vm. We will append more to
this recipe.

The following kernel config fragments must be manually enabled,
i.e. in local.conf, to use this test suite.
KERNEL_FEATURES_append += "features/bpf/bpf.scc \
                        cfg/debug-kselftest.scc \
                   features/hugetlb/hugetlb.scc \
"
