libbpf: Change bpf_object_skeleton data field to const pointer
This change was necessary to enforce the implied contract
that bpf_object_skeleton->data should not be mutated. The data
will be cast to `void *` during assignment to handle the case
where a user is compiling with older libbpf headers to avoid
a compiler warning of `const void *` data being cast to `void *`
