x86-64: Remove kernel.vsyscall64 sysctl
It's unnecessary overhead in code that's supposed to be highly
optimized. Removing it allows us to remove one of the two
syscall instructions in the vsyscall page.
The only sensible use for it is for UML users, and it doesn't
fully address inconsistent vsyscall results on UML. The real
fix for UML is to stop using vsyscalls entirely.
