xfs: add a define for statfs magic to uapi
Needed by userspace programs that call fstatfs().
It'd be natural to publish XFS_SB_MAGIC in uapi, but while these two
have identical values, they have different semantic meaning: one is
an enum cookie meant for statfs, the other a signature of the
on-disk format.
