8206456 - [TESTBUG] docker jtreg tests fail on systems without cpuset.effective_cpus / cpuset.effective_mem

[Baesken, Matthias]

Hi Bob, looks good  (I am not a Reviewer however) !

The reported issues occured on a  SUSE Linux 12 SP1 system ,  where 

/sys/fs/cgroup/cpuset/cpuset.effective_cpus     and       /sys/fs/cgroup/cpuset/cpuset.effective_mems    are  not present .

I applied  Bobs patch ,  now  the  jdk/internal/platform/docker  -  jtreg  tests do not fail any more on the mentioned system .

Thanks, Matthias
