ci: remove test while investigation is undergoing

The test removed by this change currently hangs during the Linux boot
process. Our investigations have yielded no obvious underlying cause, so
we have handed this investigation over to the FVP team to identify a
potential model bug.

This issue is tracked by SDDKW-100855.
