[PATCH] xfs: report projid32bit feature in geometry call

When xfs gained the projid32bit feature, it was never added to
the FSGEOMETRY ioctl feature flags, so it's not queryable without
this patch.

note1: is there a reason we had gaps in the flags?
note2: I don't *think* this requires a new version for the ioctl
