[Buildroot] [PATCH v2 1/1] tzdata: Reorder zone list to avoid missing links

[Michel Marti <mma@objectxp.com>]

The 'backward' zone references entries from other zones (e.g. Pacific/*)
that have not yet been compiled, leading to missing links. To fix this,
take-over the zone list sort order from upstream 'tzdata' and also ensure
that make fails if zic terminates with a non-zero exit code.
