Subject: libbpf: Fix compilation warning due to mismatched printf format
Patch-mainline: v5.18-rc1
Git-commit: dc37dc617fabfb1c3a16d49f5d8cc20e9e3608ca
References: jsc#PED-1377
On ppc64le architecture __s64 is long int and requires %ld. Cast to
ssize_t and use %zd to avoid architecture-specific specifiers.
Fixes: 4172843ed4a3 ("libbpf: Fix signedness bug in btf_dump_array_data()")
