util: add guards for the etrace/trace defines

Browse source 
This file is really useful on its own for other projects if
auto-included via export CFLAGS="$CFLAGS -include /path/to/file.h"
However, that causes compiler warnings, let's add indef checks for this
as a quick workaround.

Since these three come as a set and are only used for debugging, we can
ifndef them all in one go rather than individually.
