[PATCH wayland 7/8] tests: add possibility to disable leak check for single test

[Marek Chalupa]

In tests that are using external libraries (i. e. pthread) we
can get failure because of leaks in the external library.
Until we have some better solution (if ever), let these (and only these)
tests to disable leak checks.
