Tests 1.1.9 and 1.1.10 sometimes failing running command

[yoavrotems]

Test 1.1.9 is running the following command

audit: |
          ps -ef | grep $kubeletbin | grep -- --cni-conf-dir | sed 's%.*cni-conf-dir[= ]\([^ ]*\).*%\1%' | xargs -I{} find {} -mindepth 1 | xargs stat -c permissions=%a
          find /var/lib/cni/networks -type f 2> /dev/null | xargs --no-run-if-empty stat -c permissions=%a

Sometimes the first part ps -ef | grep $kubeletbin | grep -- --cni-conf-dir | sed 's%.*cni-conf-dir[= ]\([^ ]*\).*%\1%' | xargs -I{} find {} -mindepth 1 returns empty value, and stat couldn't run with empty value.
Command needs to be

audit: |
          ps -ef | grep $kubeletbin | grep -- --cni-conf-dir | sed 's%.*cni-conf-dir[= ]\([^ ]*\).*%\1%' | xargs -I{} find {} -mindepth 1 | xargs --no-run-if-empty stat -c permissions=%a
          find /var/lib/cni/networks -type f 2> /dev/null | xargs --no-run-if-empty stat -c permissions=%a

Same apply to 1.1.10
