Only log the sending of regular packets in sender_t

When sender_t is used to send ESP packets this would otherwise cause an extreme
amount of debug messages.
With this change all messages sent via sender_t.send_no_marker() cause no extra
DBG1 log message, but for debugging purposes the socket plugins do log the same
message again with DBG2 for all packets.
