[MAPREDUCE-6486] File{Input|Output}Format counters not updated when using viewfs

Description

MapReduce tasks rely on filesystem stats to update FileInputFormatCounter and FileOutputFormatCounter bytes counters.

But if the filesystem is viewfs, stats are not updated and counters are zero. However the resolved filesystem for the input and output paths have their stats updated, and should be used by the framework (which could be done by resolving the path first).
