add WITH_DBUG_TRACE CMake variable

Browse source 
This is a way do disable DBUG_ENTER()/DBUG_EXIT() stuff which is
needed to dbug trace. Those who doesn't need it may avoid tests
slowdown with -DWITH_DBUG_TRACE=OFF

dbug/tests.c: add define which is neede always in this test

innodb.log_file_name_debug.test: do not depend on DBUG trace stuff
in test

Benchmark results: each test eats less CPU and you can have more
parallel jobs in MTR.
