test: relax fixedbugs/issue20250.go expectations

With GOEXPERIMENT=unified, the order variables are printed in "live at
entry to f.func1" is sensitive to whether regabi is enabled for some
reason. The order shouldn't matter to correctness, but it is odd.

For now, this CL just relaxes the test expectation order to unblock
enabling GOEXPERIMENT=unified by default. I've filed #54402 to
investigate further to confirm this a concern.

Updates #54402.
