I wonder why the defines exist at all? My grep doesnt find SUID_DUMP_*.
Looking at the commit message from d6e711448137ca3301512cec41a2c2ce852b3d0a

    Actually the feedback I had from last time was that the SUID_ defines
    should go because its clearer to follow the numbers. They can go
    everywhere (and there are lots of places where dumpable is tested/used
    as a bool in untouched code)

Exporting a random array size is not very useful. The app and the kernel
has to check the string length anyway.

So lets remove the header and the 3 unused defines.
