Reuse asm-x86-64/unistd.h to build our syscall table, like x86-64 already
does.
Like for i386, we must add some #defines for all the (right!) changes
UML does to x86-64 syscall table.
Note: I noted a bogus:
[ __NR_sched_yield ] = (syscall_handler_t *) yield,
while doing this patch (which could only be a workaround for some strange bug,
but I would ignore this possibility). I'm changing this without notice.
