[bug#70280] [PATCH 2/5] system: ‘operating-system-locale-definitions’ includes the OS’ locale.

[Ludovic Courtès]

* gnu/system.scm (<operating-system>)[locale-definitions]: Mark as
thunked.  Default to (operating-system-default-locale-definitions os).
(operating-system-default-locale-definitions): New procedure.
(operating-system-locale-directory): Remove logic to add the OS
‘locale’, instead assuming (operating-system-locale-directory os) has
everything.
* doc/guix.texi (operating-system Reference): Adjust accordingly.
