samples, bpf: Refactor kprobe, tail call kern progs map definition
Because the previous two commit replaced the bpf_load implementation of the user program with libbpf, the corresponding kernel program's MAP definition can be replaced with new BTF-defined map syntax. This commit only updates the samples which uses libbpf API for loading bpf program not with bpf_load. Signed-off-by: Daniel T.
