[PATCH v3 4/4] 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The counting busy loop has been replaced by an interval based busy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. While at it: Enable this test for CI. It was previously marked
as broken. The counting busy loop was not enough to keep the task alive.
