Update SPPatchify.ps1

As mentioned in #23 the disabling of the "W3SVC" service results in SharePoint 1603 errors/installation errors. After that, you can't run the PSCONFIG. You need to restart the installation with the "W3SVC" service enabled. Then everything runs fine. So I have deleted the "W3SVC" from the service -startuptype disabled.
