[Buildroot] [git commit] sudo: fix main executable permissions

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=0e8dafcb3e1ddb7935c1c8c305e7e5598be30315
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
