mtd-utils: upgrade 2.1.6 -> 2.2.0

This is a small release of changes that have accumulated since last August.
As it contains mainly new command line switches (i.e. features) for some
of the tools, this receives a minor version bump.

The Autotools based build system also received a slight overhaul, cleaning
up how configure switches and dependencies are handled. It should now
also be possible to compile mtd-utils without requiring zlib.
