Register IonHeapSize puller only if supported
IonHeapSize atom can be created only if kernel exposes a sysfs node with
the information, otherwise 0 is returned.
Register the puller conditionally only if the sysfs node is present.
This avoids the overhead of creating the atom and simplifies the
server-side configuration.
