tests: PROXY_URL is more accurately PROXY_HOST

Change the `GITTEST_REMOTE_PROXY_URL` environment variable to be
`GITTEST_REMOTE_PROXY_HOST`, since it is a host:port combination, not an
actual URL.  (We cannot use a URL here since we may want to include the
username:password combination in the constructed URL.)
