The reason, why the module can not be built are, as the error suggest, missing kernel header files.
Install them with
sudo apt-get install linux-headers-generic
It will install a meta-package that always points to the latest kernel headers in the repository. If a new kernel is available and installed during a system update, the appropriate headers are going to be installed automatically as well.
Afterwards, try to install the vboxdrv modules again.
