complete the EC autoupdate mechanism and vboot code.

Useful when debugging to determine if a user has an official build or
not, particularly early in the devel process where we're handing
builds to everyone. Particularly useful for proto1, since not all
those systems will be case-open servo-attached.
Also move get-version LPC command into system.c, where it's closer to
the system functions it calls (matches what we do for other host
commands).
