Fix failing `npu-xrt` tests

[mawad-amd]

#2455 added Peano to the run tests CI which turned on some of the previously unsupported tests but some of them are segfaulting.

The current disable tests are:

  AIE_TEST :: npu-xrt/dma_complex_dims/aie2.py
  AIE_TEST :: npu-xrt/dma_task_large_linear/aie2.py
  AIE_TEST :: npu-xrt/objectfifo_repeat/compute_repeat/aie2.py
  AIE_TEST :: npu-xrt/objectfifo_repeat/distribute_repeat/aie2.py
  AIE_TEST :: npu-xrt/objectfifo_repeat/init_values_repeat/aie2.py
  AIE_TEST :: npu-xrt/vec_vec_add_objfifo_init/aie2.py

(Assigning fifield since he may have a couple of local fixes.)

these are fixed by #2505

npu-xrt/objectfifo_repeat/compute_repeat/aie2.py
npu-xrt/objectfifo_repeat/init_values_repeat/aie2.py
npu-xrt/vec_vec_add_objfifo_init/aie2.py

these are fixed by #2505

npu-xrt/objectfifo_repeat/compute_repeat/aie2.py
npu-xrt/objectfifo_repeat/init_values_repeat/aie2.py
npu-xrt/vec_vec_add_objfifo_init/aie2.py

I think this one is also solved:
npu-xrt/objectfifo_repeat/distribute_repeat/aie2.py

#2551
The same fix as in #2505 works for npu-xrt/dma_task_large_linear/aie2.py but not the other one.
