[PATCH v3 3/4] testsuite/smokey/vxworktests: Fix compile error seen with gcc 16

Fixes the following error:

task-2.c: In function ‘backgroundTask’:
task-2.c:26:42: error: variable ‘count’ set but not used [-Werror=unused-but-set-variable=]
   26 |         unsigned int safety = 100000000, count = 0;
      |                                          ^~~~~
cc1: all warnings being treated as errors

The busy waiting loop is keeping the background task alive, so that
the foreground task is able to call taskSuspend() for the background
task.

Replacing the counting busy loop with a call to taskDelay(), which will
be time based. We will stay in the RT domain while waiting, so that
taskSuspend() is called for a task part of the RT domain.
