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

    gio-tool-info: Print unix mount information where available
    
    "gio info" output doesn't contain any information about unix mounts, which
    is a pity, because such info can be used for debugging purposes as various
    functionality depends on g_unix_mount_at() resp. g_unix_mount_for(). Let's
    print unix mount info and local path if available.
