Prepare to support taking CLDR data from its github upstream

We've previously used the zip-file form, but that's not been published
for CLDR v44.1 - the advice on the list was to use github
instead. That, however, has ↑↑↑ as a special value for fields, meaning
to inherit from a prent locale. So special-case that value. I have
verified that v44 from the zip file produces identical results to v44
from github, with this minor fix. As it happens v44.1 also produces
identical results.

Pick-to: 6.7 6.5
