Log:
  capsicum_helpers: Add FIODTYPE to default ioctls allowed
  
  FIODTYPE will be needed by hexdump(1) to speed up the -s flag on devices
  that should be able to support fseek(3); specifically, in an attempt to
  correct for the fact that most tape drives don't support seeking yet don't
  indicate as such when fseeko(3) is invoked. Related: D10939
