test: ignore EPIPE errors in https proxy invalid URL test

There can be a race from eagerly shutting down the servers and severing two pipes at the same time but for the purpose of this test, we only care about whether the requests are initiated from the client as expected, not how the upstream/proxy servers behave. Ignore EPIPE errors from them. PR-URL: #60269 Refs: #59741 Reviewed-By: Luigi Pinca <luigipinca@gmail.com> Reviewed-By: Yagiz Nizipli <yagiz@nizipli.com>
