jz4670_tools: add usbboot tool, tweak Makefile and packtool
Although the jz4740 contains a similar tool to usbboot, its command-line interface is not very useful, also it does not compile by default because it relies on some external code, and it contains code specific to some JZ4740 devices. Change-Id: I22688238d147e21fb0fd524466b333b6003d4ff1
