[master/f20/rhel7] Ignore SIGINT (#971323)

Resolves: rhbz#971323
Ignore SIGINT instead of doing the default action. Also, remove the
KeyboardInterrupt handling in the pyanaconda thread manager since these
threads should never see a Keyboard Interrupt.
There is a justification for this:
1) There's some way of exiting all set up screens, and
2) Interrupting the actual install is a bad idea, and
3) If you know what you're doing you can send it a kill signal which it will
still obey.
