return test_slps to installcheck-local with time,zap io limits

[baallan]

this checks the return code and wraps test_slps in 'timeout' so it cannot hang forever, should a transport hang occur.

@nichamon, did you get a chance to review this?

[nichamon]

I checked that the line that sets the returned code had been removed. I saw the "no-kokkos blocking ok" messages in the build-test-ubuntu workflow. I didn't confirm that the "no-kokkos blocking test timed out" messages will be reported if the test_slps script gets timeout.

@baallan can you resolve the conflicts in this pull request?

I rebased to top of tree; checking into what's causing the distcheck fails.

[baallan]

test_slps is failing in the transport layer in something rails related.
Nothing new in this patch is at fault, but if it is merged, then installcheck will be failing, possibly due to test code which has not caught up with recent rails api changes.
I've ported this patch to the 441rc2 branch as a separate pr #1300
