net/http/httputil: permit nil request body in ReverseProxy
Accepting a request with a nil body was never explicitly supported but
happened to work in the past.
This doesn't happen in most cases because usually people pass
a Server's incoming Request to the ReverseProxy's ServeHTTP method,
and incoming server requests are guaranteed to have non-nil bodies.
Still, it's a regression, so fix.
Fixes #12344
