Kernel/riscv64: Generate Kernel.bin from kernel ELF

Browse source 
This is necessary for being able to use the qemu `-kernel` option.
The QEMU virt machine uses OpenSBI's FW_DYNAMIC feature to pass
the kernel entry address, which is the virtual entry point address
specified in the kernel ELF. If we instead `objcopy` the kernel into a
raw binary, OpenSBI will jump to the physical kernel load address, which
is what we want it to do.
