update_kernel: Save .5 seconds by avoiding tmp copy for kernel image

Browse Source 
There's no need to store to a temporary file when updating the kernel
partition.  Just stream straight to the right partition.  This appears
to save about .5 seconds.

BUG=None
TEST=Time update_kernel and see savings; verify that kernel still gets
updated.
