Fix #53957 by revising unit test to focus on underlying bug of #23076.
Namely, this version focuses on the end-to-end behavior that the attempt to create the UDP binding will fail, regardless of the semantics of how particular DNS servers handle junk inputs.
(I spent some time trying to create a second more-focused test that would sidestep the DNS resolution, but this is not possible without more invasive changes to the internal infrastructure of
ToSocketAddrs
and what not. It is not worth it.)
