Subject: doc: clarify the operation of uniq -uD

The description of -u was inaccurate when combined with -D:

  $ printf '%s\n' '1 a' '2 a' | uniq -uD -f1
  1 a

* doc/coreutils.texi (uniq invocation): Clarify that it's
the last repeated line that is suppressed from the output.

Fixes http://bugs.gnu.org/17022
