arm64: use {COMPAT,}SYSCALL_DEFINE0 for sigreturn
We don't currently annotate our various sigreturn functions as syscalls, as we need to do to use pt_regs syscall wrappers. Let's mark them as real syscalls. For compat_sys_sigreturn and compat_sys_rt_sigreturn, this changes the return type from int to long, matching the prototypes in sys32.c.
