linux-user, arm: add syscall table generation support

Browse source 
Copy syscall.tbl and syscallhdr.sh from linux/arch/arm/tools/syscalls v5.5
Update syscallhdr.sh to generate QEMU syscall_nr.h

Update syscall.c to manage TARGET_NR_arm_sync_file_range as it has
replaced TARGET_NR_sync_file_range2

Move existing stuff from linux-user/Makefile.objs to
linux-user/arm/Makefile.objs
