vboot/secdata_mock: Make v0 kernel secdata context
The new kernel secdata v1 stores the last read EC hash, and reboots the device during EC software sync when that hash didn't match the currently active hash on the EC (this is used with TPM_CR50 to support EC-EFS2 and pretty much a no-op for other devices). Generally, of course the whole point of secdata is always that it persists across reboots, but with MOCK_SECDATA we can't do that. Previously we always happened to somewhat get away with presenting freshly-reinitialized data for MOCK_SECDATA on every boot, but with the EC hash feature in secdata v1, that would cause a reboot loop. The simplest solution is to just pretend we're a secdata v0 device when using MOCK_SECDATA. This was encountered on using a firmware built with MOCK_SECDATA but had EC software sync enabled. BUG=b:187843114 BRANCH=None TEST=`USE=mocktpm cros build-ap -b keeby`; Flash keeby device, verify that DUT does not continuously reboot with EC software sync enabled.
