Fix WHOIS formatting to match format from RA

Our whois format was flagged as wrong in the .meet PDT. Although
we had followed the AWIP samples from ICANN, the definitive list
of field names is from Specification 4 of our contract, available at
https://newgtlds.icann.org/sites/default/files/agreements/agreement-approved-09jan14-en.htm
and indeed our fields are incorrect. (The remaining formatting issues
are ambiguous but the PDT testers' interpretation is probably correct.)

Since the footer format is now somewhat more complicated, I also denormalized
the disclaimer field into all of the testdata files. (I spent some time
debugging an extra newline between the content and the disclaimer, and
it would have been far clearer to solve if the files had been this way.)
