setup: don't spin on EOF in setup_interactively()

If you hit ^D during interactive setup it'd send things
infinitely spinning.

This commit treats eof when expecting more input as -EIO and
simply gives up.  Which I imagine technically means it's possible
to terminate the last interactive question with EOF/^D instead of
newline and have it work, since we only check it before the
fgets() used to get more input.
