Evaluate a grsec kernel from spender's build service in Tails

1. add the needed .deb’s from spender’s build service to config/chroot_local-packages/
2. modify --linux-packages= in auto/config
3. try building an ISO
4. apply any needed dirty hack until the ISO builds and boots (e.g. it might be needed, for this first iteration, to disable building dkms modules, disable syslinux CPU architecture autodetection, etc.)
5. boot the resulting ISO
6. manually test some features
7. run the automated test suite against that ISO
8. report back :)
