add gitk to gui meta package
bump kernel, grsec, gradm to linux 3.8
remove old grsecurity patch

when i added this patch, i didnt notice how huge it was -
it'so huge it clutters the commit history of sabotage itself.

to not make this error again, grsec patches are now tarred up
and provided as a separate package, on which the kernel pkg
depends on.

theoretically this patch should have been removed together with
the linux 3.8 bump commit, however that would have made that
commit very slow to load, so i do it in a seperate commit.
