do not include timestamps in .gz files of docs

The timestamps in the .gz files are not used for anything, and they break
the reproducibility of the build.  Giving --no-name means gzip will not
save the filename and timestamp in the gz file itself.  When gunziping, the
current file name will be used, minus the .gz suffix.
