Kui-Feng Lee 0232b78897 bpftool: Register struct_ops with a link.
You can include an optional path after specifying the object name for the
'struct_ops register' subcommand.

Since the commit 226bc6ae64 ("Merge branch 'Transit between BPF TCP
congestion controls.'") has been accepted, it is now possible to create a
link for a struct_ops. This can be done by defining a struct_ops in
SEC(".struct_ops.link") to make libbpf returns a real link. If we don't pin
the links before leaving bpftool, they will disappear. To instruct bpftool
to pin the links in a directory with the names of the maps, we need to
provide the path of that directory.
