Tests: do not bound test app iterations when in background mode

On systems with a high number of CPUs and slow disk, taking snapshots
can take a long time. When running a long regression test, the tests
sometimes outlive the test application.

The test application then exits since the required number of
iterations was completed
(NR_ITER=2000000).

Set the iterations parameter to -1 to ensure the application keeps
producing events for the duration of the test.
