tests/malloc: cleanup in test application

Browse Source 
The idea is not fill the memory on the computer running a native instance and to be able to test on hardware. The test application is reworked similarly as the memarray test application. Macro are now overridable and printed at the beginnined of the test: this allows easier automatic testing
