update wget 1.20.2 (security fix and new release)

This is a new release of wget 1.20.2 (April 1, 2019). I successfully
downloaded install64.iso as a test. Of note: "Fixed a buffer overflow
vulnerability." I just wanted to get this new version out first. I will
look into how to download the corpus of tests to reactivate fuzz tests
in a future diff.
