bcachefs: Move BCACHEFS_STATFS_MAGIC value to UAPI magic.h
Move BCACHEFS_STATFS_MAGIC value to UAPI <linux/magic.h> under BCACHEFS_SUPER_MAGIC definition (use common approach for name) and reuse the definition in bcachefs_format.h BCACHEFS_STATFS_MAGIC. There are other bcachefs magic definitions: BCACHE_MAGIC, BCHFS_MAGIC, which use UUID_INIT() and are used only in libbcachefs. Therefore move only BCACHEFS_STATFS_MAGIC value, which can be used outside of libbcachefs for f_type field in struct statfs in statfs() or fstatfs().
