wget 1.16.1

This release brings the --disable-pcre flag, and this commit
makes that flag take effect unless you pass --with-pcre to the
brew install.  Pcre is not a requirement, but wget
opportunistically (and silently) links to it if it's on your
machine, which can make for nasty surprises later.

Closes #34842.
Closes #34857.
