In the build system, rename 'makefile.ezt' to build-outputs.mk.ezt' to make
it easier to find, since it is the source file for 'build-outputs.mk'.

* build/generator/gen_make.py
  (Generator): Update the filename passed to ezt.Template().

* build/generator/templates/makefile.ezt
  Rename to ...
* build/generator/templates/build-outputs.mk.ezt
  ... this, and update the self-reference in the 'do not edit' comment.
