wget: Update to 1.16 (fix CVE-2014-4877)

This patch updates wget to the current version, 1.16. This release fixes a
remotely exploitable security issue: CVE-2014-4877.

A dependency on libidn was added and the testsuite now depends on
python3. A patch that disables a test was removed because it is not needed
anymore.

As I intend to take care of wget in the future, I added myself to the
maintainers.
