CTRL-D produces error instead of a graceful exit

[dizcza]

Steps to Reproduce (for bugs)

1. use exploits/routers/linksys/eseries_themoon_rce
2. set a target
3. run
4. (inside a cmd) hit CTRL-D

Expected Behavior

Gracefully exit cmd payload and return back to routersploit main menu.

The same behavior occurs when I try reverse_tcp payload inside a cmd

Do y'all have any idea what causes these?
