[klibc] dash: main: Print \n upon EOF (CTRL-D) when run interactively

[ dash commit 413c6dcc3ca3891825ae8239251140882d7c6c6c ]

Exiting dash via a ^D instead of with "exit" causes dash to forget to
print a newline.

    sh-3.1$ sh
    sh-3.1$ ^D
    sh-3.1$ dash
    $ sh-3.1$

It is more neat and tidy to send a newline similarly to what bash does,
so it doesn't make the next prompt of the parent shell look ugly.

Suggested by jidanni.
