Allow EDM files and TFiles to be specified in the outputFiles flag.

The JobType.outputFiles parameter is used for the user to specify additional output files that should be collected on top of the EDM and TFileService output files. Currently, if the user by mistake specifies one EDM or TFileService output file in this parameter, the job will inject to CouchDB twice (same doc id, with different 'job_end_time' and 'last_update' values). This patch is to ignore EDM file names and TFileService file names specified in the JobType.outputFiles parameter.
