usbip: update userspace to match kernel part

usbip: update userspace to match kernel part

After kernel 2.6.39, usbip kernel and userspace are in kernel tree
The new kernel modules names have already been updated in openwrt for
kernel > 2.6.39

This patch, allow to build the new corresponding usbip userspace tool
when of the device use a kernel > 2.6.39
And continue to build version 0.1.7 for older version.

Fix #10992

Florian:
- do not use an md5sum for usb.ids since it changes often
- dropped the parts to support kernels <= 2.6.39
- make the package depend on LINUX_3_3
