Unreviewed. Change the format string portable by using "%" PRIx64
instead of "%llx" for uint64_t argument.

This patch removes the build warning below since r252978.

warning: format ‘%llx’ expects argument of type ‘long long unsigned int’,
but argument 3 has type ‘JSC::SpeculatedType {aka long unsigned int}’ [-Wformat=]

(JSC::PredictionFileCreatingFuzzerAgent::getPredictionInternal):
