nvidia-x11-legacy{340,304}: fix build with linux-3.18

Browse source 
Close #9218.
It's our default kernel (now and for the upcoming release).
- 304 won't build with 4.1,
- 173 didn't even build with 3.14 due to other issues (3.12 is OK ATM)
- all legacy drivers are up-to-date with upstream releases.
