VolumeVerifier: Add extra validity checks for ticket and TMD

This fixes VolumeVerifier potentially calling TMDReader::GetIOSId for
invalid TMDs.

VolumeVerifier also has a call to TMDReader::GetContent that doesn't
check if the TMD is valid. In practice, this can't get called with an
invalid TMD because the previous commit made it so GetContentOffsets
returns an empty vector if the TMD is invalid, but I've added a check
inside TMDReader::GetContent just to be on the safe side.

I also made VolumeVerifier show a specifically worded problem if the
ticket or TMD is invalid. Before, invalid TMDs in Wii discs and WADs
and invalid tickets in WADs would show a more generic problem.
