Add new V4L2_FMT_FLAG_EMULATED flag to videodev2.h
From: Hans de Goede <hdegoede@redhat.com>
V4L2_FMT_FLAG_EMULATED 0x0002 This format is not native to the device but
emulated through software (usually libv4l2), where possible try to use a
native format instead for better performance.
Priority: normal
