[lldb] Disable TestProcessSaveCoreMinidumpSizeMismatch on Windows hosts (#214044)

The buildbot
[lldb-remote-linux-win](https://lab.llvm.org/buildbot/#/builders/197) is
red after #212861. #212861 cannot be reverted automatically now because of
#212641. So disable TestProcessSaveCoreMinidumpSizeMismatch on Windows
hosts to make the buildbot green again.
