curl: Add patch to fix CVE-2022-43551

Add patch to fix the security issue "curl's HSTS check could be bypassed
to trick it to keep using HTTP. Using its HSTS support, curl can be
instructed to use HTTPS instead of using an insecure clear-text HTTP
step even when HTTP is provided in the URL." as per below link
