Checkmk Werk 12713: check_ps: Check goes UNKN if configured to show percentage of RAM in some cases

ID: 12713 Title: check_ps: Check goes UNKN if configured to show percentage of RAM in some cases Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 check_ps was not configured to use data from <<<statgrab_mem>>> section which made the total RAM unavailable on systems providing <<<statgrab_mem>>> rather than <<<mem>>>, rendering "Process" Services UNKNOWN. This change makes check_ps use <<<statgrab_mem>>> again, restoring the behavior of version 1.6.0 and below.
