[ci] Fixing flaky rocprim tests

[geomin12]

Noticing errors such as:

      Start 46: rocprim.device_select
Error: The action 'Test' has timed out after 60 minutes.

36 - rocprim.device_reduce_by_key (Timeout)

We also ignore the following tests:

TESTS_TO_IGNORE = "rocprim.lookback_reproducibility|rocprim.linking|rocprim.device_merge_inplace|rocprim.device_merge_sort|rocprim.device_partition|rocprim.device_radix_sort|rocprim.device_select|rocprim.device_find_first_of|rocprim.device_reduce_by_key"
