mtd-utils: Add configure switches to disable jffsX or ubifs tools
For some applications, like building a root filesystem for an embedded device, it may be desireable to only build and install a subset of the mtd-utils. This can be done throught the targets of the generated Makefile and hand picking executables, however the jffsX and ubifs utilities have external build dependencies that may not be needed. This patch adds configure switches to disable building the jffsX and ubifs utilities. Their respective build dependencies (zlib, lzo, uuid) are only requested if the tools are being built.
