tools/bpf: sync kernel header bpf.h and add bpf_task_fd_query in libbpf
Sync kernel header bpf.h to tools/include/uapi/linux/bpf.h and implement bpf_task_fd_query() in libbpf. The test programs in samples/bpf and tools/testing/selftests/bpf, and later bpftool will use this libbpf function to query kernel.
