bpftool: Fix -Wuninitialized-const-pointer warnings with clang >= 21
This fixes the build with -Werror -Wall.
btf_dumper.c:71:31: error: variable 'finfo' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
71 | info.func_info = ptr_to_u64(&finfo);
| ^~~~~
prog.c:2294:31: error: variable 'func_info' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
2294 | info.func_info = ptr_to_u64(&func_info);

v2:
- Initialize instead of using memset.
