net/http: enable WASM fetch where supported
The existing check was introduced to allow tests to pass
on WASM without an environment where the fetch RoundTripper
could run. However, the check now prohibits the use of the
Fetch RoundTripper in all WASM tests, even where the
RoundTripper could run. The new change should only disable
the RoundTripper when used in an environment without fetch.
Fixes #32289
