fix: default enable_negotiate_port to false

[nornagon]

Description of Change

The default value of this was switched from false to true in this CL, which we inherited as part of the M69 upgrade. I'm unsure, but I think this might be responsible for #17111 and similar Kerberos-related issues. In any case, it makes sense to keep the default the same as before (and the same as Chrome, which forces this option to false, despite the interface defaulting it to true).

See https://chromium.googlesource.com/chromium/src/+/69.0.3497.128/net/http/http_auth_handler_negotiate.cc#142 for some context about what this feature does.

Release Notes

Notes: Fixed a regression in Kerberos SPN generation. In the M69 upgrade, the default for the enable_negotiate_port option was inadvertently changed from false to true; this restores the former behavior and aligns with Chromium.
