* mount.h (fs_info::fsn): New member. 

(fs_info::clear): Clear fsn.
	(fs_info::fsname): New read accessor for fsn.
	* mount.cc (fs_info::update): Fill in fsn member with lowercased
	filesystem name if filesystem is not well-known.  Fall back to
	"unknown" if filesystem name is missing.
	(fillout_mntent): Print filesystem name retrieved in fs_info::update
	rather than static string "unknown".
