ovsdb-tool: Workaround inability to replace existing file on Windows.

rename() on an existing destination file fails on Windows. This commit
worksaround that problem.

There are two tests that test it. But both of them use the ovsdb-server's
--run option for the test and it does not exist in Windows. So change
the test to workaround the lack of that feature.
