[tracker-miners/wip/carlosg/apps-in-miner-fs: 8/10] tracker-miner-fs: Index application dirs

[Carlos Garnacho <carlosg src gnome org>]

commit d13fd8b28a7c95a1f1bced33052e456eb9cce3a0

    tracker-miner-fs: Index application dirs
    
    This is the second step towards folding tracker-miner-apps into
    tracker-miner-fs. The TrackerIndexingTree has been made to also
    index system/user application directories, which does the scaffolding
    for tracker-extract to index those.
