patchMakefile: correct the dependency graph of hook-list.h

Fix an issue in my cfe853e66be (hook-list.h: add a generated list of hooks, like config-list.h, 2021-09-26), the builtin/help.c was inadvertently made to depend on hook-list.h, but it's used by builtin/bugreport.c.

The hook.c also does not depend on hook-list.h. It did in an earlier version of the greater series cfe853e66be was extracted from, but not anymore. We might end up needing that line again, but let's remove it for now.

For this commit there were no changes or outstanding comments, except that in [3] it was suggested that this more isolated fix by split-up from the rest.
