Fix SNSPowderRedux system tests for alma9 (#39231)

When starting to work to migrate from centos7 to alma9
(mantidproject/dockerfiles#111), some tests
failed as seen in [build
205](https://builds.mantidproject.org/job/Core_Team_test_pipeline/205/).
The failing tests (in case the log disappears) are
`SystemTests.SNSPowderRedux.PG3Analysis`,
`SystemTests.SNSPowderRedux.PG3StripPeaks`, and
`SystemTests.BayesQuasiTest.BayesQuasiTest`. This fixes the
SNSPowderRedux tests by updating the reference results after manually
inspecting them.

There is also a minor change to the test which reduces the runtime of
the test by 2-3 seconds.
