suricata: move WindowsInitService to SuricataMain

Move WindowsInitService from SuricataInit() to SuricataMain(), as
initializing Suricata as a service is very specific to the application
and not something you'd want to happen in a library, and SuricataInit
is more common initialization for application and library usage.
