Tests: Introduce gen-ust-events-constructor test application

Tests: Introduce gen-ust-events-constructor test application

This test application tests C/C++ constructor/destructor instrumentation coverage.

* How to use:

lttng create
lttng enable-event -u 'tp*'
lttng start
./gen-ust-events-constructor
lttng stop
lttng view
