[GLIB] kill-old-processes report stderr messages if task could not be found
Created attachment 407596 [details] Patch
When killall command is applied to a non-running process or to an empty string, there's stderr output which might be a bit misleading. For instance, https://ews-build.webkit-uat.org/#/builders/35/builds/5370/steps/6/logs/stdio The patch filters out stderr.
