bpf_helpers_doc.py: Fix warning when compiling bpftool
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")
