We shouldn't be upcasting our file instances. Given a
PartitionFilesystem is currently designed to accept any arbitrary
VfsFile instances, casting to a more specific type than that is just bad
design, and shows an interface design issue.
Previously is_hfs and pfs_header members wouldn't be initialized in the
constructor, as they were stored in locals instead. This would result in
things like GetName() and PrintDebugInfo() behaving incorrectly.
While we're at it, initialize the members to deterministic values as
well, in case loading ever fails.
