net: fix USB network driver config option.
It must be tristate to avoid broken dependencies with kernel built-in
usb network drivers when usb support is module only.
When net config option is set, least surprize default should match usb.
Wireless RNDIS USB driver used to select USB_USBNET. USB_USBNET now
depends on USB_NET_DRIVERS so the latter should be selected as well.
