- `processor_count` was erroneously set to the number of cores
- `processor_cores` was erroneously set to the number of threads per core
- `processor_vcpus` and `processor_threads_per_core` were not set
- `processor` was a string, while it's supposed to be a list
Before:
```
"ansible_processor": "PowerPC_POWER7",
"ansible_processor_cores": 4,
"ansible_processor_count": 12,
```
After:
```
"ansible_processor": [
"PowerPC_POWER7"
],
"ansible_processor_cores": 12,
"ansible_processor_count": 1,
"ansible_processor_threads_per_core": 4,
"ansible_processor_vcpus": 48,
```
Also add a unit test.
