systemc: Update the ordering in the reference output for some tests.

systemc: Update the ordering in the reference output for some tests.

There are a number of cases where systemc leaves the decision of what
order things happen up to the kernel, and any ordering is legal and
conformant with the spec as long as it's repeatable. The reference
outputs reflect a particular choice of ordering which is implementation
specific, and while considerable effort has been made to make the gem5
ordering match the Accellera ordering, at a certain point that's no
longer practical or desirable.

This change manually updates the reference output for the tests that
haven't been excluded for other reasons which have this sort of ordering
problem. They have been individually examined, and as best as I can
tell changing the output this way does not mask any underlying error.

One or two real problems were discovered in addition to the ordering
issues, and those were fixed in earlier changes.
