conf: Automatically use NUMA memory size in case NUMA is enabled

Browse Source 
Use the NUMA total instead of the configured size both in XML and for
uses in the code once NUMA is enabled for a domain.

One test case change is necessary as the rounding of the individual cell
sizes was not matching the rounding of the total size.
