revert the update as the new wget version links to libunistring
that is a rather large library. Better to revert the update now
in order to fix buildbot and then look into solutions.

wget 1.91.1 configure script tries to link libunistring
if that is found. That lib is rather large and is not that
essential for normal operations, so instead of depending
on that, try to avoid linking it.

Revert an upstream commit that removed the clearance of
libunistring data in case IRI is explicitly disabled
(like we have it).
