* cuda: New version 10.1.243
Adds CUDA 10.1.243. The installer command-line arguments have slightly
changed, hence in the install method the version needs to be inspected
in order to give the correct arguments for the new installer.
* cuda: Combine common command-line arguments
The CUDA 10.1+ installer has slightly different command-line arguments
than previous versions. Keep the common parts together and only split
where they are different.
