Turn on USE=lockvt for daisy

USE=lockvt tells the power manager to lock VT's on suspend/resume and
not use a suspend console.  This should speed up the UI becoming
visible on resume and workaround an issue with the wrong VT being
displayed on resume.

BUG=chrome-os-partner:12471
TEST=Rapid suspend/resumes via lid switch, could not reproduce
  the case where screen is blank on resume.
  Observed VT lock log messages in powerm.LATEST
