Checkmk Werk 11973: Be more precise if include files are missing

ID: 11973 Title: Be more precise if include files are missing Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Checkmk no longer ships '*.include' files in the 'checks/' directory (see <a href="https://checkmk.com/de/werk/11118">Werk #11118</a>). In case you have MKPs installed that need them (but do not include them themselves) you must either update your MKP or provide the required files in the 'local' folder hierarchy. The error message now reports the correct path where to put the file.
