MFC r336551:
Add missing dtrace probes for received UDP packets.

Fire UDP receive probes when a packet is received and there is no
endpoint consuming it. Fire the probe also if the TTL of the
received packet is smaller than the minimum required by the endpoint.

Clarify also in the man page, when the probe fires.
