update_kernel: Only copy stuff in /boot if doing syslinux

In normal Chrome OS flows (other than the syslinux flow), we don't use
"/boot" for booting the system.  Normally Chrome OS loads the kernel
from the kernel partition (KERN-A or KERN-B).

Copying stuff in /boot just takes extra time and disk space.  Let's
not do it.

After this change, I find myself running out of disk space much less
frequently when running update_kernel (assuming I pass --nosyslinux).

BUG=None
TEST=Try with and without the "--nosyslinux" flag.
