update_kernel: Learn arch from board build (redux)
The boot.desc file in a build contains the information about what arch
the build is for. But sometimes that file isn't built, e.g. when a dev
has only built the kernel and not a whole image. Parse the kernel config
file for the architecture instead and pass it along to vbutil. This
avoids SSH to the DUT just to run uname.
BUG=None
TEST=update kernel on Cheza works
