Makefile: drop CHECK_HEADER_DEPENDENCIES codejk/make-simplify-dependencies
This code was useful when we kept a static list of header files, and it was easy to forget to update it. Since the last commit, we generate the list dynamically. Technically this could still be used to find a dependency that our dynamic check misses (e.g., a header file without a ".h" extension). But that is reasonably unlikely to be added, and even less likely to be noticed by this tool (because it has to be run manually)., It is not worth carrying around the cruft in the Makefile.
