Subject: doc: Allow different translations for 'guix-cookbook' and
 'guix-manual'.

Previously, 'guix-manual-text-domain' could be passed the cookbook
language list as its second argument.  Thus, it started failing when the
set of cookbook languages was no longer a subset of the manual
languages, starting with commit
93bfd4d9c7ba7055c19f02128491b3a98a180860, which removed "sk" from
'guix-manual' but kept it for 'guix-cookbook'.

* doc/build.scm (%manual-languages, %cookbook-languages): New
variables.
(%languages): Use them.
(guix-manual-text-domain): Give LANGUAGES a valid default value.
(localization-helper-module): Remove optional argument to
'guix-manual-text-domain'.
