Brett Porter 0c7c143ad1 fix escaping of powershell variable
As this is nested in a powershell variable $command, it must be escaped
otherwise it is evaluated when the variable is created, giving an error that
"The term 'True' is not recognized as the name of a cmdlet, function,
script". This prevented using a puppet.working_directory on Windows.
