linux-generic: packet_io: use generic interface for pktio implementations

Each packet_io type now implements a pktio_if_ops_t structure which serves
as the only interface use by odp_packet_io.c.
The type of a device is retrieved by calling the pktio_XX open function in
order from the global pktio_if_ops struct and by stopping on the
first successful order.

As a result odp_pktio_type_t has been removed, and implementation can
be extended by just adding a new pktio_if_opts_t structure to pktio_if_opts
