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

[Ondrej Holy <oholy src gnome org>]

commit b7083a35d28715da55ce27a5eae2838c4a3a3abd

    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.
