bpftool: Add link dump support for BPF_LINK_TYPE_SOCKMAP
An example output looks like:
$ bpftool link
1776: sk_skb prog 49730
map_id 0 attach_type sk_skb_verdict
pids test_progs(8424)
1777: sk_skb prog 49755
map_id 0 attach_type sk_skb_stream_verdict
pids test_progs(8424)
1778: sk_msg prog 49770
map_id 8208 attach_type sk_msg_verdict
pids test_progs(8424)
