[ Upstream commit 22c349e8 ]

There are some mismatches between format strings and arguments passed to
jsonw_printf() in the BTF dumper for bpftool, which seems harmless but
may result in warnings if the "__printf()" attribute is used correctly
for jsonw_printf(). Let's fix relevant format strings and type cast.

Fixes: b12d6ec0 ("bpf: btf: add btf print functionality")
