net: add missing SOF_TIMESTAMPING_OPT_ID support

Browse source 
SOF_TIMESTAMPING_OPT_ID is supported on TCP, UDP and RAW sockets.
But it was missing on RAW with IPPROTO_IP, PF_PACKET and CAN.

Add skb_setup_tx_timestamp that configures both tx_flags and tskey
for these paths that do not need corking or use bytestream keys.

Fixes: 09c2d251b7 ("net-timestamp: add key to disambiguate concurrent datagrams")
