Kernel: Remove the "kernel info page" used for fast gettimeofday()
We stopped using gettimeofday() in Core::EventLoop a while back, in favor of clock_gettime() for monotonic time. Maintaining an optimization for a syscall we're not using doesn't make a lot of sense, so let's go back to the old-style sys$gettimeofday().
