[Buildroot] [PATCH] sudo: fix main executable permissions

[spdawson at gmail.com]

From: Simon Dawson <spdawson at gmail.com>

The sudo executable is installed without the setuid bit set, which prevents
sudo from working.

This patch adds a post-install hook to fix the permissions of the sudo
executable.
