[Buildroot] [PATCH] package/lynx: add security patch for CVE-2021-38165

[Buildroot] [PATCH] package/lynx: add security patch for CVE-2021-38165

[Peter Korsgaard]

Lynx through 2.8.9 mishandles the userinfo subcomponent of a URI, which
allows remote attackers to discover cleartext credentials because they may
appear in SNI data.

Upstream unfortunately does not provide a public VCS (only source
snapshots), so fetch the security patch from Debian.
