libtracker-miner: Use g_file_equal() to check for file equality

This is about the only place where we do actually rely on TrackerFileSystem
using "const" pointers to the same GFile above TrackerFileNotifier. It's
actually not that much of a hotspot, so use g_file_equal() here, and check
it early in the function to make it easier to read.
