vlib: copy trace_handle in vlib_buffer_copy/clone() functions
Since vlib_buffer_copy() and vlib_buffer_clone() both preserve VLIB_BUFFER_IS_TRACED bit in flags field, it should also copy trace_handle which would add minimal overhead. Thus, callers of these functions do not have to call vlib_buffer_copy_trace_flags() to copy trace_handle.
