[glib/wip/oholy/gio-info-mount: 1/2] gio-tool-info: Print unix mount information where available

[Ondrej Holy <oholy src gnome org>]

commit 5589faf76b729ce22f899af6b344b142eee2441e

    gio-tool-info: Print unix mount information where available
    
    "gio info" output doesn't contain any information about mount points, but
    that information can be useful when debugging issues in facilities that
    depend on knowing about mount points, such as the trash API.
