linux-user, ppc: add syscall table generation support
Copy syscall.tbl and syscallhdr.sh from linux/arch/ppc/kernel/syscalls v5.5
Update syscallhdr.sh to generate QEMU syscall_nr.h
and to not generate the entry if entry point is sys_ni_syscall.
Fix ppc/signal.c to define do_sigreturn() for TARGET_ABI32.
