__u64 maybe an unsigned long, it may also differ from the format
expected by PRIu64. Add a cast to silence the warning:

tools/lib/perf/tests/test-evsel.c:176:33: error: format specifies type 'unsigned long long' but the argument has type 'unsigned long' [-Werror,-Wformat]
                __T_VERBOSE("count = %llu\n", end - start);
                                     ~~~~     ^~~~~~~~~~~
                                     %lu
