busybox 1.34.1 ash: ^C exit the shell

[leessangbobo]

We have been using busybox 1.31.0 in the past, but recently upgraded to version 1.34.1 to fix vulnerabilities in AWK and Hush.
Accidentally,CTRL+C will exit the current shell terminal directly, which was not the case in 1.31.0.
And notice that on the master branch, there's a commit ' ash: ^C with SIG_INGed SIGINT should not exit the shell '
May I apply this patch to fix the problem which I mentioned?
Thanks.
