tui: Fix newterm call for older ncurses

Older versions of ncurses' newterm can't take NULL for their ofp and ifp
parameters. Newer versions can, and they fall back on stdout/stdin if
that is the case.

This patch explicitly passes stdout/stdin to the call to newterm to
avoid segfaulting with older ncurses.
