Lioncash 0149162dba filesystem: Make CreateFactories() and InstallInterface() take a VfsFilesystem instance by reference 
Neither of these functions alter the ownership of the provided pointer,
so we can simply make the parameters a reference rather than a direct
shared pointer alias. This way we also disallow passing incorrect memory values like
nullptr.
