Expose the usb_iodev_vuart_setup function in uartproxy. This opens
the secondary ACM pipe to new uses outside the hypervisor. E.g. it can
be set up as another stream for sending proxy requests.
Sample usage from proxyclient:
p.usb_iodev_vuart_setup(p.iodev_whoami())
p.iodev_set_usage(IODEV.USB_VUART, USAGE.UARTPROXY)
# the second virtual serial now also serves proxy
