python3-pip: set CVE_STATUS for CVE-2018-20225

Analysis:
- NVD marks CVE-2018-20225 as disputed. [1]
- pip searches all configured package indexes without priority and selects
  the highest matching version. --extra-index-url adds an equal-priority
  package source. [2]
- Exploitation requires use of --extra-index-url and an attacker-published,
  higher-version package with the name of a private package. [1]
- Upstream closed the related report as not planned, and Red Hat classified
  the issue as WONTFIX because this behavior is intentional. [3][4]
- Record the disputed status; no source patch is available.
