nodeinfo: make nodeGetInfo() call nodeGetMemory for memory size

The nodeGetInfo() method currently has its own code for getting
memory size in KB, that basically just re-invents what nodeGetMemory
already does. Remove it and just call nodeGetMemory, converting its
result from bytes to KB, allowing removal of more platform specific
conditional code.
