[PATCH v2] libubootenv: generate reproducible source tarball

["srinuvasan.a via isar-users" <isar-users@googlegroups.com>]

From: srinuvasan <srinuvasan.a@siemens.com>

Apply additional options to the tar command used to generate
reproducible source tarball: (1) use numeric and null [GU]IDs,
-clamp-mtime for file modification times to never be later than
SOURCE_DATE_EPOCH (preserving mtimes for files not modified by
the recipe) and --sort=name for consistent ordering within the
archive.
