selftests/bpf: Add weak/typeless ksym test for light skeleton

Also, avoid using CO-RE features, as lskel doesn't support CO-RE, yet. Include both light and libbpf skeleton in same file to test both of them together. In c48e51c8b07a ("bpf: selftests: Add selftests for module kfunc support"), I added support for generating both lskel and libbpf skel for a BPF object, however the name parameter for bpftool caused collisions when included in same file together. This meant that every test needed a separate file for a libbpf/light skeleton separation instead of subtests. Change that by appending a "_lskel" suffix to the name for files using light skeleton, and convert all existing users.

selftests/bpf: Add verif_stats test

verified_insns field was added to response of bpf_obj_get_info_by_fd call on a prog. Confirm that it's being populated by loading a simple program and asking for its info.
