Fallback information not propagated to StatisticsSenderService

[makortel]

While investigating a question of @perrotta in #36358 (comment) I realized that after #28911 the RootInputFileSequence::usedFallback_ was no longer set, and consequently StatisticsSenderService was no longer reporting this information in

cmssw/Utilities/StorageFactory/src/StatisticsSenderService.cc

Lines 236 to 238 in a1d2ae9

	if (usedFallback) {
	os << "\"fallback\": true, ";
	}

(also Tracer attempts to use the usedFallback information e.g. in

cmssw/FWCore/Services/plugins/Tracer.cc

Lines 531 to 537 in a1d2ae9

	void Tracer::preOpenFile(std::string const& lfn, bool b) {
	LogAbsolute out("Tracer");
	out << TimeStamper(printTimestamps_);
	out << indention_ << indention_ << " starting: open input file: lfn = " << lfn;
	if (dumpNonModuleContext_)
	out << " usedFallBack = " << b;
	}

)
