bpftool: Fix a wrong type cast in btf_dumper_int
[ Upstream commit 7184aef9c0f7a81db8fd18d183ee42481d89bf35 ]
When `data` points to a boolean value, casting it to `int *` is problematic
and could lead to a wrong value being passed to `jsonw_bool`. Change the
cast to `bool *` instead.
Fixes: b12d6ec09730 ("bpf: btf: add btf print functionality")
