rewrite build system to avoid recursion

The ubi-utils/src/ subdir is tossed as it just complicates things for no
real gain.  The dictionary.h header is relocated to the ubi-utils/include/
since other headers in there need it.

The top level clean is replaced with a `find -delete` on objects, so it
might prune more than necessary, but many projects now do this sort of
thing and no one complained there.

A "mkdep" helper generates the actual rule, and the variables are used
with "foreach" to expand these automatically.

The tests subdir is updated only to reflect the ubi-utils source move.
Otherwise, it is left untouched as making that non-recursive isn't really
worth the effort.

While we're gutting things, also through in kbuild style output while
building to make things more legible.
