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
