sched: Always show Cpus_allowed field in /proc/<pid>/status

Browse Source 
The Cpus_allowed fields in /proc/<pid>/status is currently only
shown in case of CONFIG_CPUSETS. However their contents are also
useful for the !CONFIG_CPUSETS case.

So change the current behaviour and always show these fields.
