util-linux: correct test case kill/decode for bash 5.3

After upgrading bash to 5.3 to contain commit [1], if SIGINT was trapped in
asynchronous subshell, bash called set_signal_async_ignored to make sure
processes that are created by this asynchronous subshell to ignore SIGINT.

And it caused test case `kill/decode' failed, the signal INT was existed in
both of Blocked and Ignored

Explicitly reset SIGINT to default action after trapping, then the
test case `kill/decode' works on both of old (<5.3) and new (>=5.3) bash
