Add m68k seccomp definitions to seccomp_bpf self test code.
Tested on ARAnyM.
Signed-off-by: Michael Schmitz <schmitzmic@xxxxxxxxx>

Changes from v12:
Michael Karcher:
- use correct definition of ARCH_REGS (use of struct pt_regs
cause stack overflow on passing register set to user space
due to size mismatch, and has some register offsets wrong)
