sim: delete duplicate SIGINT handling
Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:
sigsave = signal (SIGINT, interrupt);
However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.
