Add a way to install Nvidia libraries offline

NVIDIA_HANDLER now has two installation modes. 

In the first (default) mode Conty downloads the driver from the official Nvidia website and installs it inside the container. In the new second mode Conty simply copies Nvidia libraries from the host system.

If the first mode fails for some reason (for example, there is no internet connection), Conty automatically tries the second mode. It is possible to force Conty to always use the second mode by using NVIDIA_HANDLER=2 variable.
