bpftool: Support sysctl hook
Add support for recently added BPF_PROG_TYPE_CGROUP_SYSCTL program type
and BPF_CGROUP_SYSCTL attach type.
Example of bpftool output with sysctl program from selftests:
# bpftool p load ./test_sysctl_prog.o /mnt/bpf/sysctl_prog type cgroup/sysctl
# bpftool p l
9: cgroup_sysctl name sysctl_tcp_mem tag 0dd05f81a8d0d52e gpl
