curl: fix CVE-2025-0167

When asked to use a `.netrc` file for credentials *and* to
follow HTTP redirects, curl could leak the password used
for the first host to the followed-to host under certain
circumstances.

This flaw only manifests itself if the netrc file has a
`default` entry that omits both login and password. A
rare circumstance.
