http2: avoid race in TestTransportReqBodyAfterResponse_403.

This test sends a request with a 10MiB body, reads a 403 response
while the body is still being written, and closes the response body.
It then verifies that the full request body was not written, since
reading a response code >=300 interrupts body writes.

This can be racy: We process the status code and interrupt the body
write in RoundTrip, but it is possible for the body write to complete
before RoundTrip looks at the response.

Adjust the test to have more control over the request body:
Only provide half the Request.Body until after the response headers
have been received.

Fixes golang/go#48792.
