 Testsuite: mark T4945 as expect_broken (#4945)

 In commit 7d519dabd2006c9742e82fce02df55704da15482, the file
 T4945.stdout was added to the repository, to make T4945 pass
 validatation presumably.

 When that test produces output however, there is a bug somewhere, and we
 shouldn't hide it. There is a comment in the Makefile which says:

     "When SpecConstr works there are no STUArrays at all"

 So here we remove T4945.stdout again, mark T4945 as expect_broken, and
 reopen the ticket.
