[PATCH] Makefile: correct the dependency graph of hook-list.h

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

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.

As noted in [1] this is the first of smaller topics that split-up and
replace the ab/make-dependency topic. Range-to the previous start of
the series below. The v4 of the old series is at [2].

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.
