usbip: tools: fix build error for multiple definition

Origin: https://lore.kernel.org/lkml/20200618000844.1048309-1-borneo.antonio@gmail.com/

With GCC 10, building usbip triggers error for multiple definition
of 'udev_context', in:
- libsrc/vhci_driver.c:18 and
- libsrc/usbip_host_common.c:27.

Declare as extern the definition in libsrc/usbip_host_common.c.
