samples/bpf: allow make to be run from samples/bpf/ directory
It is not intuitive that 'make' must be run from the top level directory with argument "samples/bpf/" to compile these eBPF samples. Introduce a kbuild make file trick that allow make to be run from the "samples/bpf/" directory itself. It basically change to the top level directory and call "make samples/bpf/" with the "/" slash after the directory name. Also add a clean target that only cleans this directory, by taking advantage of the kbuild external module setting M=$PWD.

Do notice the "/" slash after the directory name.
+It is also possible to call make from this directory. This will just
+hide the the invocation of make as above with the appended "/".
