Enhance vlib_buffer_clone to change headroom space for packet
Add function vlib_buffer_clone_at_offset() so that the cloned
packets' 1st buffer will have the original packet header copied
at the specified offset (instead of current_data). This can be
used to increase headroom in the cloned packet to allow large
header encaps in case the stdandard 128B predata is not enough.
The original vlib_buffer_clone() still works the same as before.
