By adding libbpf into perf's Makefile, this patch enables perf to build libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set. The newly introduced code is similar to how libapi and libtraceevent are wired into Makefile.perf. MANIFEST is also updated for 'make perf-*-src-pkg'. Append make_no_libbpf to tools/perf/tests/make. The 'bpf' feature check is appended into default FEATURE_TESTS and FEATURE_DISPLAY, so perf will check the API version of bpf in /path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except when we are trying to port this code to an old kernel. Error messages are also updated to notify users about the lack of BPF support in 'perf record' if libelf is missing or the BPF API check failed. tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf files when working on perf using tools/perf/tags.
