gh-131178: remove runtime tests for http.server CLI (#134287)

The runtime behavior of `http.server` CLI is hard to test on an arbitrary platform.
As such, tests asserting the correctness of `python -m http.server` are temporarily
removed and will be rewritten later once a universal solution has been found.
