Crossbuilding selftests/bpf for architecture arm64, format specifies
type error show up like.

xskxceiver.c:912:34: error: format specifies type 'int' but the argument
has type '__u64' (aka 'unsigned long long') [-Werror,-Wformat]
 ksft_print_msg("[%s] expected meta_count [%d], got meta_count [%d]\n",

                                                                %llu
                __func__, pkt->pkt_nb, meta->count);
                                       ^~~~~~~~~~~
xskxceiver.c:929:55: error: format specifies type 'unsigned long long' but
 the argument has type 'u64' (aka 'unsigned long') [-Werror,-Wformat]
 ksft_print_msg("Frag invalid addr: %llx len: %u\n", addr, len);
                                    ~~~~             ^~~~

Fixing the issues by casting to (unsigned long long) and changing the
specifiers to be %llu from %d and %u, since with u64s it might be %llx
or %lx, depending on architecture.
