Always define missing TAILQ functions from sys/queue.h

On both Android and Ubuntu machines, TAILQ_END is not defined.  This
header also does not seem to be part of standard BSD sys/queue.h

Fix this by always defining missing TAILQ_ macros rather than
conditioning on a particular macro.

Fixes #267
