[Mageia-dev] Freeze push: sudo

[David Walser]

This updates to bugfix release 1.8.6p6.

- On systems where the controlling tty can be determined via /proc or sysctl(), sudo will no longer fall back to using ttyname() if the process has no controlling tty. This prevents sudo from using a non-controlling tty for logging and time stamp purposes.

I've confirmed that it builds and works fine in Cauldron.
