bpftool: Use __typeof__() instead of typeof() in BPF skeleton
When generated BPF skeleton header is included in C++ code base, some
compiler setups will emit warning about using language extensions due to
typeof() usage, resulting in something like:
error: extension used [-Werror,-Wlanguage-extension-token]
obj->struct_ops.empty_tcp_ca = (typeof(obj->struct_ops.empty_tcp_ca))
^
It looks like __typeof__() is a preferred way to do typeof() with better
C++ compatibility behavior, so switch to that. With __typeof__() we get
no such warning.
Fixes: c2a0257c1edf ("bpftool: Cast pointers for shadow types explicitly.")
Fixes: 00389c58ffe9 ("bpftool: Add support for subskeletons")
