tools/lib/libbpf.c: fix string format to allow build on arm32
On arm32, 'cd tools/testing/selftests/bpf && make' fails with: libbpf.c:80:10: error: format ‘%ld’ expects argument of type ‘long int’, but argument 4 has type ‘int64_t {aka long long int}’ [-Werror=format=] (func)("libbpf: " fmt, ##__VA_ARGS__); \ ^ libbpf.c:83:30: note: in expansion of macro ‘__pr’ #define pr_warning(fmt, ...) __pr(__pr_warning, fmt, ##__VA_ARGS__) ^~~~ libbpf.c:1072:3: note: in expansion of macro ‘pr_warning’ pr_warning("map:%s value_type:%s has BTF type_size:%ld != value_size:%u\n", To fix, typecast 'key_size' and amend format string.
