Support signing kernel in update_kernel script.

Browse Source 
This CL is separated from http://gerrit.chromium.org/gerrit/#change,1104 which
is depends on the UUID replacement. In order to make update_kernel not break on
officail ChromeOS firmware, this CL just signs the kernel and use the original
cmdline approach, i.e. /dev/${devname}${rootpart}.

TEST=./update_kernel --remote IP
