Installation fails for non-threaded Perl

When I try to install Net::Server on a Perl that isn't built with thread support the tests in t/Server_Thread.t cause the installation to fail.

From the cpanm install log:

I built on Ubuntu 22.04 with a self-brewed perl (using perlbrew install 5.30.3) and then do a cpanm -L local Net::Server.
