Update test data for entitled license test

[ Merge of http://go/wvgerrit/199355 ]

A new set of license data was created on UAT so that we
could have keys that match those in the license returned by
a License SDK and by those generated by UAT.

It should be more clear now which data is just made up, and
which data has to match some golden values based on the made
up data.
