kvm: Load kernel at 0x1000

Browse Source 
As described in Documentation/x86/boot.txt, memory starting at 0x1000 is
available for the boot loader.  As we don't have a separate boot loader, load
the kernel at the address.  Note: we're setting up the segment selector here so
0x0100:0x0000 in 16-bit real mode is 0x1000 in physical memory.
