[WINESYNC] msi: Don't assume that WoW64 redirection is enabled in custom_start_server().

Browse source 
As of 3a884c2ef the server is started on the main thread, so this is no
longer a valid assumption. In particular, we disable WoW64 redirection while
running standard actions, including the top-level INSTALL action.
