[PATCH v4 2/3] testsuite/smokey/psostests: Fix compile error seen with gcc 16

Fixes the following compile errors:

rn-1.c: In function ‘alloc_task’:
rn-1.c:16:18: error: variable ‘n’ set but not used [-Werror=unused-but-set-variable=]
   16 |         int ret, n;
      |                  ^
rn-1.c:15:22: error: variable ‘alloc_size’ set but not used [-Werror=unused-but-set-variable=]
   15 |         u_long size, alloc_size = 0;
      |

task-2.c: In function ‘backgroundTask’:
task-2.c:19:42: error: variable ‘count’ set but not used [-Werror=unused-but-set-variable=]
   19 |         unsigned int safety = 100000000, count = 0;
      |                                          ^~~~~
cc1: all warnings being treated as errors

The counting busy loop has been replaced by an interval based busy
loop. The counting busy loop was not enough to keep the task alive.
That is most likely the reason why the test had to be disabled on
smokey level (and with that for CI).
