vpd: Add ICC provisioning task.
Some devices ship with device-specific ICC color calibration
written to the VPD. This data must be provisioned before the
ui starts so that ash can pick it up from a known directory.
This task creates the directory, then invokes vpd_icc, which
provisions the calibration data from the VPD, if any.
