Kernel: Expand the kernel memory slot from 8 MiB to 16 MiB

Browse source 
We were only 448 KiB away from filling up the old slot size we reserve
for the kernel above the 3 GiB mark. This expands the slot to 16 MiB,
which allows us to continue booting the kernel until somebody takes
the time to improve our loader.
