Update sh/kernel-ck-ubuntu

Updated to 3.7.9.
This will be the end of a nice period.
We'd had a great time with 3.7.x-ck patches and it was my pleasure to make pull requests, but 3.7.x is reaching it's EOL.

PS: See you soon in 3.8.x series :)
PPS: I also want to thank you again for this script.
