Handle 'Unknown' as measurement value. (#1113)

Browse source 
We use the output-compatible perccli and storcli.py does not handle 'Unknown' as a result:
```
sg="Error parsing \"/var/lib/node_exporter/perccli.prom\": text format parsing error in line 222: expected float as value, got \"Unknown\"" source="textfile.go:212"
```
I know, the perccli should not return 'Unknown' but this error breaks all other useful measurements because the prom file is not parsable. My if condition fixes this.
