Sometimes, one mount path may be encountered multiple times
in /proc/self/mounts file.
For example, when systemd automounting is used.
In such cases Filelight would display such mount paths multiple times
in main window.
Or when multiple filesystems are mounted over same path.
In such cases use information only about last mounted filesystem
since only it is available at the moment.

Also ignore 'autofs' filesystems.
