[cpesuggest] Add CPE prefix for third_party/boringssl/README.chromium.

To verify the correctness of the suggested CPE Prefix, please follow the
steps below:
1. Visit the National Vulnerability Database (NVD) page for the suggested
   CPE Prefix here: https://nvd.nist.gov/products/cpe/search/results?namingFormat=2.2&keyword=cpe:/a:google:boringssl&status=FINAL%2CDEPRECATED
2. Check whether the third-party dependency for which the CPE Prefix is
   suggested matches the project listed in the NVD page.
3. If the open source project matches and the CPE prefix is not deprecated,
   please Code-Review+1 and submit if you have enough votes.
4. If the open source project does not match or if the CPE prefix is
   deprecated, please add the incorrect suggestion to go/ignored_cpes_textproto
   and add the reason why the suggestion is incorrect.

Adding CPE prefixes to a README.chromium file is recommended practice [1] to
enable automated vulnerability monitoring. For more information on how CPE
prefixes are used see the Chromium Third Party docs [2].
