    Due to a different size of ino_t ustat needs a compat handler, but
    currently only x86 and mips provide one.  Add a generic compat_sys_ustat
    and switch all architectures over to it.  Instead of doing various
    user copy hacks compat_sys_ustat just reimplements sys_ustat as
    it's trivial.  This was suggested by Arnd Bergmann.
    
    Found by Eric Sandeen when running xfstests/017 on ppc64, which causes
    stack smashing warnings on RHEL/Fedora due to the too large amount of
    data writen by the syscall.
