SERVER-7252 Produce correct commandline for Windows service for --install, --reinstall or --service.

The service command line is derived from the mongod/mongos command line when Mongo is started with
--install, --reinstall and --service.  It does this by stripping out options that describe how to
install the service, and correctly quoting the arguments.  This patch makes this procedure more explicit,
and handles the equals sign and arguments with spaces and backslashes in the process.
