Subject: bpf_helpers_doc.py: Fix warning when compiling bpftool
Patch-mainline: v5.7-rc1
Git-commit: 5996a587a466fa469531272139d23a3b56e07e5c
References: bsc#1177028

When compiling bpftool the following warning is found: "declaration of
'struct bpf_pidns_info' will not be visible outside of this function."
This patch adds struct bpf_pidns_info to type_fwds array to fix this.

Fixes: b4490c5c4e02 ("bpf: Added new helper bpf_get_ns_current_pid_tgid")
