Fix #4293 - Use OperatingSystems::Match::WINDOWS

Fix #4293. Modules should use OperatingSystems::Match::WINDOWS instead of Msf::OperatingSystems::WINDOWS, because the second won't match anything anymore.

To verify:

All the modules can be verified the same way. I'm just gonna use advantech_webaccess_dvs_getcolor as an example:

- [x] Set up a Windows box. In my test, I used a Windows 7.
- [x] Start msfconsole
- [x] Do: ```use exploit/windows/browser/advantech_webaccess_dvs_getcolor```
- [x] Run the module
- [x] When your IE browser visits the malicious link, you should not see "os_name" being an unmet requirement.
