TINSEL: Fix support for file names with a trailing dot

When copying data files with 8.3 names from a CD, they sometimes end up
with a trailing dot, e.g. "INDEX." instead of "INDEX". Comon::File
supports this, but in r54392 Tinsel stopped using Common::File.

This commit also removes the useless SeekableSubReadStream wrapper
around the actual file stream.
