components: SANVITO EMV-Testsuite (refs #33211)

* modified several test-cases to reduce CPU and system load,
  to make the tests run stable even with the CPU clocked to only 400 MHz

This test-load still causes temperature issues with the current SANVITO hardware
without any kind of CPU-cooler and causes the CPU to reduce the clock-speed to
only 400 MHz after some runtime, until the CPU-temperature falls low enough
again (which does actually happen and work with this test.)
