cpuset_memory_pressure from ubuntu_ltp_controllers times out on B/F node akis

[Kleber Sacilotto de Souza]

Testcase cpuset_memory_pressure from ubuntu_ltp_controllers times out on bionic/linux 4.15.0-162.170 on node akis:

This is not a regression as this testcase is not timing out on other nodes and akis has been recently added to the test pool and is failing since we started running ubuntu_ltp_controllers on it.
