Cause TestLib.pm to define $windows_os in all branches.
Back-port of a part of commit 690ed2b76ab91eb79ea04ee2bfbdc8a2693f2a37 that
I'd depended on without realizing that it was only added recently. Since
it seems entirely likely that other such tests will need to be back-patched
in future, providing the flag seems like a better answer than just putting
a test in-line.
Per buildfarm.
