Use sigaction() instead of signal()

Issue is that even after ctrl+c, fgets is waiting for a newline.

See signal(7) for details.  We have to either use siginterrupt() together with
signal(), or use sigaction() instead of signal() for registering the signal
handler, in order to disable restarting a read() system call after a signal.
