arm64: add seccomp support
secure_computing() is called first in syscall_trace_enter() so that a system call will be aborted quickly without doing succeeding syscall tracing if seccomp rules want to deny that system call. On compat task, syscall numbers for system calls allowed in seccomp mode 1 are different from those on normal tasks, and so _NR_seccomp_xxx_32's need to be redefined.
