    tracker-miner-fs: Check for mountpoint file eligibility
    
    This is a revert/modernization of commit 98ec9cdec0. The check is
    still necessary since indexing tree roots don't get checked the
    same after added.
    
    This results in unrelated mountpoints being unintendedly indexed.
    Spotted in grilo-plugins tests, and pinpointed to that commit by
    Marinus Schraal.
