ash: let ignoreeof only affect interactive shells
Commit fb7d6c89 from Harald van Dijk's gwsh variant of ash
(https://github.com/hvdijk/gwsh):
ignoreeof is documented as only having an effect for interactive shells,
but is implemented as having mostly the same effect for interactive
shells as for non-interactive shells. Change the implementation to match
the documentation.
Test case:
$SHELL -o ignoreeof /dev/null
function old new delta
cmdloop 359 361 +2
