linux-user: proper exit code for uncaught signals
The proper exit code for dieing from an uncaught signal is -<signal>.
The kernel doesn't allow exit() or _exit() to pass a negative value.
To get the proper exit code we need to actually die from an uncaught signal.
A default signal handler is installed, we send ourself a signal
and we wait for it to arrive.
