protect online DQM clients when running in inputFiles mode against meaningless customizations

[mmusich]

PR description:

Title says it all.
When developing a test for CMSHLT-3534 I realized that certain online client configurations customize the event source as if it was a DQMStreamerReader even in the case it which options.inputFiles is not null. In that case as per this code here:

cmssw/DQM/Integration/python/config/inputsource_cfi.py

Lines 125 to 132 in 6a7da0e

	else:
	print("The list of input files is provided. Disabling discovery and running on everything.")
	files = ["file://" + x for x in options.inputFiles]
	source = cms.Source("PoolSource",
	fileNames = cms.untracked.vstring(files),
	secondaryFileNames = cms.untracked.vstring()
	)

the source gets changed to a traditional PoolSource and the customization doesn't make sense, hence leading to runtime errors.
This PR introduces protections to circumvent the issue.
