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

[wchen-r7]

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:

• Set up a Windows box. In my test, I used a Windows 7.
• Start msfconsole
• Do: use exploit/windows/browser/advantech_webaccess_dvs_getcolor
• Run the module
• When your IE browser visits the malicious link, you should not see "os_name" being an unmet requirement.
