Adithya Baglody 24c96a8a47 tests: benchmarks: sys_kernel: Enable benchmark for slower SoCs
Few SoCs whose clock speed is very less will cause multiple ticks
to occur for 1 sec of sleep. For such a platform we cant run
the loops for over 5000 because the tick handler will get executed.
Thus rendering the test useless for such platforms. By reducing
the number of iterations we get the required benchmark results.

Fixes: GH-7906

Title: kernel Object Performance

Description:

The SysKernel test measures the performance of semaphore,
lifo, fifo and stack objects.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console. It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
