VolumeVerifier: Remove SystemNotAvailable

We had some code in VolumeVerifier to catch the error message that
Redump.org used to show when trying to access the Wii datfile without
logging in. This restriction was removed from Redump.org around the
start of 2022, and the code has been unnecessary ever since.
