netdevsim: Set offsets to various protocol layers
The driver periodically generates "trapped" UDP packets that it then
passes on to devlink. Set the offsets to the various protocol layers.
This is a prerequisite to the next patch, where drop monitor is taught
to check that the offset to the MAC header was set.
