Description
Use the portable integer format macros from <inttypes.h> for 64-bit values in libbpf-tools, and explicitly cast lost-event counters passed to variadic logging functions. This avoids assuming that Linux __u64 is always unsigned long long, which breaks builds on ppc64le where it is unsigned long.
The change covers the libbpf-tools format sites that would otherwise trigger -Werror=format, including the failure reported in #5330.
Testing
Fixes #5330
