libcurl: security bump to version 7.86.0

Version 7.85.0 fixes CVE-2022-35252: When curl retrieves and parses
cookies from an HTTP(S) server, it accepts cookies using control codes
(byte values below 32). When cookies that contain such control codes are
later sent back to an HTTP(S) server, it might make the server return a
400 response. Effectively allowing a "sister site" to deny service to
siblings.

Drop upstream patches and autoreconf.
