bug#26238: core-updates: Fix time zone bug in `date` 8.26

I think ‘coreutils-final’ doesn’t need the replacement because the
‘coreutils’ package that we get on GuixSD or when typing ‘guix package
-i coreutils’ is not ‘coreutils-final’.

‘-final’ is only used as an implicit input of ‘gnu-build-system’, where
the ‘date’ bug is arguably not a problem.

So for ‘coreutils-final’, I’d just do:

  (replacement #f)

WDYT?

For good measure, ‘coreutils-minimal’ should also have:

  (source (package-source coreutils/fixed))

so that it gets the fix (nothing depends on ‘coreutils-minimal’, so
there’s no need for a graft here.)

Thanks!
