Re-enable a test for non-Windows

[probinson]

Summary

Required teaching lit.cfg.py to distinguish Windows the same way other projects do.

This should be system-windows. See config.py in llvm. By using system-windows, the test would be consistent with other platforms. Incidentally, I am just about to fix this as well as the test in LLVM that you changed to use windows - it should also use system-windows.

lldb/lit/lit.cfg.py

This really should live in config.py in llvm so that it can be used across all projects. And it should be system-windows for consistency with other platforms.

@stella.stamenova fixed this using system-windows instead.
