wget: enable libpsl

[samueloph]

Build with libpsl to turn on Public Suffix List checks, so cookies can't be set for broad public suffixes like .co.uk; this blocks "supercookies" that would otherwise be shared across unrelated sites under the same suffix.

Feel free to take over this PR to address any pending issues, my motivation was to point out that PSL is not enabled (very likely by mistake) and the PR was simple enough, but I don't plan on spending more time on this, sorry.
