Fix tzdata update tools for 'backzone'.

Browse Source 
To maintain the status quo, we need to pull in backzone file. This file
can't be built on its own, so the easiest fix is to give zic(1) all the
files at once.

We also now have a situation where we have links to links, so we need to
dereference them until we find actual data.
