bpf: Fix non-static bpf_func_proto struct definitions
This patch does two things:
1) Marks the dynptr bpf_func_proto structs that were added in [1]
as static, as pointed out by the kernel test robot in [2].
2) There are some bpf_func_proto structs marked as extern which can
instead be statically defined.
