[2.3.0] Checkmk Werk 15333 created: Fix parsing of win_computersystemproduct

[//]: # (werk v2) # Fix parsing of win_computersystemproduct key | value ---------- | --- date | 2024-04-29T08:53:34+00:00 version | 2.3.0p1 class | fix edition | cre component | inv level | 1 compatible | yes On some windows system `Win32_ComputerSystemProduct` seems to return no data. This call was introduced with [Werk #15332](https://checkmk.com/werk/15332) Now the parser of this data (`win_computersystemproduct`) can handle empty data. This change also reduces the data transported with the `win_computersystemproduct` section, as we only use the UUID.
