seccomp: Add missing compat_ioctl for notify
commit3db81afd99
upstream. Executing the seccomp_bpf testsuite under a 64-bit kernel with 32-bit userland (both s390 and x86) doesn't work because there's no compat_ioctl handler defined. Add the handler. Signed-off-by: Sven Schnelle <svens@linux.ibm.com> Fixes:6a21cc50f0
