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

Title: Fix parsing of win_computersystemproduct Class: fix Compatible: compat Component: inv Date: 1714380814 Edition: cre Level: 1 Version: 2.2.0p27 On some windows system <code>Win32_ComputerSystemProduct</code> seems to return no data. This call was introduced with <a href="https://checkmk.com/werk/15332">Werk #15332</a> Now the parser of this data (<code>win_computersystemproduct</code>) can handle empty data. This change also reduces the data transported with the <code>win_computersystemproduct</code> section, as we only use the UUID.
