tty-ask-pwd-agent: treat SIGINT as a request to exit immediately

Browse source 
Unlike SIGTERM, SIGINT is now treated as a request to exit as soon as
possible. IOW, if SIGINT is received, the agent wont process all remaining
passwords before exiting.

This allows a more comprehensive behavior when C-c is pressed and when the
agent is spawned by systemctl.

Before that patch, pressing C-c killed systemctl but left the agent waiting
for a password since SIGINT was blocked. The result was pretty clumsy.
