mtd-utils: Restructure the mtd-utils source.

* There is no code modification in this commit, only moving
* the files to proper place.

The user tools looks a little messy as we place almost
the all tools in the root directory of mtd-utils. To make
it more clear, I propose to introduce the following structure
for our source code.

mtd-utils/
	|-- lib
	|-- include
	|-- misc-utils
	|-- jffsX-utils
	|-- nand-utils
	|-- nor-utils
	|-- ubi-utils
	|-- ubifs-utils
	`-- tests
