[PATCH v2 01/23] bpf: move bpf_struct_ops_link into bpf.h

Move struct bpf_struct_ops_link's definition into bpf.h,
where other custom bpf links definitions are.

It's necessary to access its members from outside of generic
bpf_struct_ops implementation, which will be done by following
patches in the series.
