linux-user: Propagate siginfo_t through to handle_cpu_signal()
Currently all the architecture/OS specific cpu_signal_handler() functions call handle_cpu_signal() without passing it the siginfo_t. We're going to want that so we can look at the si_code to determine whether this is a SEGV_ACCERR access violation or some other kind of fault, so change the functions to pass through the pointer to the siginfo_t rather than just the si_addr value.
