bpf: Add missing BPF_LINK_TYPE invocations
Pengfei Xu reported [1] Syzkaller/KASAN issue found in bpf_link_show_fdinfo.
The reason is missing BPF_LINK_TYPE invocation for uprobe multi
link and for several other links, adding that.

Fixes: 89ae89f53d20 ("bpf: Add multi uprobe link")
Fixes: e420bed02507 ("bpf: Add fd-based tcx multi-prog infra with link support")
Fixes: 84601d6ee68a ("bpf: add bpf_link support for BPF_NETFILTER programs")
Fixes: 35dfaad7188c ("netkit, bpf: Add bpf programmable net device")
