Dmytro Maluka 9d2dbd3d59 selftests/cpu-hotplug: Fix check for cpu hotplug not supported
If CONFIG_HOTPLUG_CPU is disabled, /sys/devices/system/cpu/cpu*
directories are still populated, so the test fails to correctly detect
that CPU hotplug is not supported.

Fix this by checking for the presence of 'online' files in those
directories instead. The 'online' node is created for the given CPU if
and only if this CPU supports hotplug. So if none of the CPUs have
'online' nodes, it means CPU hotplug is not supported.
