Add additional items for RAID array detection

Einarc isn't detecting the following RAID controller, however adding additional fields to the `find_adapter_by_pciid` method has been successful on detecting new RAID card.

```bash
09:00.0 RAID bus controller: Adaptec AAC-RAID (rev 09)

# lspci -mn output
09:00.0 "0104" "9005" "0285" -r09 "9005" "02da"
```

Also, fix for following error:

```ruby
uninitialized class variable @@sysfs in Einarc::BaseRaid (NameError)
```

Removed the class constant inside Einarc module and moved it to `Einarc::BaseRaid` class since all adapter classes inherit BaseRaid class, and it's defined for LSI adapters mostly. 

Test suite has been updated as well to reflect the change for the @@sysfs class variable.
