Misdetecting cgroup vs cpuset naming convention

[wish]

When USE_CGROUPS is enabled the execd can misdetect whether the cpuset controlling filesystem uses the modern cgroup naming convention (cpuset.mems, cpuset.cpus)
or the older cpuset convention (mems,cpus) leading to a failure to correctly initialize the cpuset.

Patch to fix bugs #1523 and #1524

[wish]

Patch attached to this ticket. It fixes both this bug and #1524. The fix for #1524 is rather ugly but I was going for minimally intrusive rather than a major rewrite.

Anyway please apply if the ugliness doesn't bother you too much.
