[tracker-miners/wip/carlosg/no-recurse-mountpoints] libtracker-miner: Do not recurse into mount points unless configured

[Carlos Garnacho <carlosg src gnome org>]

commit 629f4646ee7804b27cd4c83fa98b865efae85ac2
Author: Carlos Garnacho <carlosg gnome org>

    libtracker-miner: Do not recurse into mount points unless configured
    
    Make TrackerFileNotifier stop recursing at folders that are mountpoints,
    this makes all files indexed in a TrackerIndexingTree root be implicitly
    from the same mount point.
    
    If there are mount points in recursively indexed folders that any user
    wants indexed, these will have to be configured as indexed folders
    themselves.
    
    Closes: https://gitlab.gnome.org/GNOME/tracker/-/issues/85
