s3: spoolss: Fix GUID string format on GetPrinter info
Fix regression introduced by commit
a4157e7c5d75 which removed the braces
around the printer GUID in the printer info level 7 structure.
MS-RPRN section 2.2 says this protocol uses curly-braced GUIDs so printers
are deleted from the directory by the domain controller's pruning service.
