self: Compute and use locale data.

Browse Source 
* guix/self.scm (sub-directory, locale-data): New procedures.
(guix-command): Add SOURCE parameter.  Call 'locale-data' when SOURCE is
true and use it in staged 'bindtextdomain' calls.
(whole-package): Add #:command and honor it.
(compiled-guix): Pass #:command to 'whole-package'.
