[XFS] fix 32-bit compat ioctls for GETXFLAGS, SETXFLAGS, GETVERSION

XFS_IOC_GETVERSION, XFS_IOC_GETXFLAGS and XFS_IOC_SETXFLAGS all take a
"long" which changes size between 32 and 64 bit platforms.

So, the ioctl cmds that come in from a 32-bit app aren't as expected, for
example on GETXFLAGS,

unknown cmd fd(3) cmd(80046601){t:'f';sz:4}

due to the size mismatch.

So, use instead the 32-bit version of the commands for compat ioctls, and
other than that it doesn't take any more manipulation.

Also, for both native and compat versions, just define them to the values
as defined in fs.h
