Fix memcg test scripts

Inspite of memcg kernel support being available, memcg_[functional|regression |stress] test script fails to execute with message

"Either Kernel does not support for memory resource controller or feature not enabled" "Skipping all memcgroup testcases...."

Fix the scripts to use proper if []; then .. fi statements.
