...eue

Backport of linux f0c24fd81f704730c529dc69aa57f21c1ade5c4e. The timestamp_type
field was introduce in later kernels, so not set in this backport.

original ommit message:
Add copying of buffer timestamps and set the timestamp_type to
V4L2_BUF_FLAG_TIMESTAMP_COPY to avoid warnings about UNDEFINED
timestamp type like:
