linux-user, mips: add syscall table generation support

Copy syscall.tbl and syscallhdr.sh from linux/arch/mips/kernel/syscalls/syscall_o32.tbl v5.5
Update syscallhdr.sh to generate QEMU syscall_nr.h
Move the offset (4000) from the file to the Makefile.objs to be passed
to syscallhdr.sh
Rename on the fly fadvise64 to fadvise64_64.
