SCI: Throw a warning in QFG import screens for unmatched files

The original SCI games supported up to 12 characters for file names, thus we
use the file name returned as a mask to find the actual file, as we don't
wrap/unwrap save file names in these screens. If no files match, or if more
than 1 files match, throw a warning.
