This adds the necessary code to init.cpp to be able to execute the first userspace process. To do this, first the filesystem code is initialized, which will use the ramdisk embedded into the kernel image. Then the first userspace process, /bin/SystemServer is executed. :^) The ramdisk code is used as it is useful for the bring-up of the aarch64 port, however once the kernel has support for better ram-based filesystems, the ramdisk code will be removed again.
