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'.
