[PATCH] seccomp: add compat_ioctl for seccomp notify

[Sven Schnelle]

Hi,

executing the seccomp_bpf testsuite with 32 bit userland (both s390 and x86)
doesn't work because there's no compat_ioctl handler defined. Is that something
that is supposed to work? Disclaimer: I don't know enough about seccomp to judge
whether there would be some adjustments required in the compat ioctl handler.
Just setting it to seccomp_notify_ioctl() makes the testsuite pass, but i'm not
sure whether that's correct.
