selftests/rdma: explicitly skip tests when required modules are missing

Currently, the rdma rxe selftests fail with an exit code of 1 when
required kernel modules are not present. This causes spurious failures
in environments where these modules might not be compiled or available.

Include the standard kselftest 'ktap_helpers.sh' and replace the
hardcoded error exits with '$KSFT_SKIP'. This ensures the tests are
properly marked as skipped rather than failed.
