vboot: when configured, pass the wipeout request to vboot 

It has become necessary to be able to "factory reset" certain devices
on firmware request.

The vboot package has been modified to provide the necessary API, this
patch introduces a configuration option and uses the API when
enabled.

CQ-DEPEND=CL:259857
BRANCH=storm
BUG=chrome-os-partner:37219
TEST=with all the patches applied, on storm, holding the recovery
     button at startup for 10 seconds, causes 'crossystem
     wipeout_request' to report '1'.
