pack: Extract populate-profile-root from self-contained-tarball/builder.
This allows more code to be reused between the various archive writers. * guix/scripts/pack.scm (set-utf8-locale): New top-level procedure, extracted from... (populate-profile-root): New procedure, extracted from... (self-contained-tarball/builder): ... here. Add #:target argument. Call populate-profile-root. [LOCALSTATEDIR?]: Set db.sqlite file permissions. (self-contained-tarball): Call self-contained-tarball/builder with the TARGET argument, and set #:local-build? to #f for the gexp-derivation call. Remove now extraneous #:target and #:references-graphs arguments from the gexp->derivation call. (debian-archive): Call self-contained-tarball/builder with the #:target argument. Fix indentation. Remove now extraneous #:target and #:references-graphs arguments from the gexp->derivation call.
