    gvfs: disable libusb support
    
    The image used in gnome-continuous has the `1.0.19` version of the
    `libusb-1.0` library. However, this version is not recent enough for
    `gvfs` to build the `libusb` support, because it needs a version
    equal or higher than `1.0.21`.
    
    Due to this not recent enough version, the `libusb` support is
    disabled.
