Install bumblebee on Ubuntu 16.10

The same as my last post, but we need to install bumblebee from testing ppa manually, because there are no packages for yakkety yet.

mkdir bumblebee-testing
cd bumblebee-testing
sudo dpkg -i *.deb

And bumblebee can work fine with steam’s games now, no need to update libstdc++ library inside steam folder.
