use_pcpu=false has incorrect behaviour with HT enabled SKUs

[ryanhamel]

The reported CPUs to slurm is the physical count, while also setting the ThreadsPerCore to 2. This effectively cuts the physical core count in half. Instead, the CPUs must always be set to the virtual count, and the ThreadsPerCore must only be 2 when use_pcpu=true. Note - Default memory per CPU must still behave correctly.
