web_shell_override: bump NOWRAP_COLS 80 -> 160 for wide ASCII banners

A survey of all libs' login banners (adm/etc/welcome|banner|motd)
found real grid-aligned ANSI art up to 154 columns wide (colon/dot
shaded pictures, not just text -- e.g. fy2005 at 99 cols, xiaoaojianghu_xo
at 154). NOWRAP_COLS=80 meant even the purpose-built "Wrap off" escape
hatch silently still wrapped and mangled these -- a user correctly
toggling wrap off got a broken banner anyway. 160 covers the full
range found (excluding one degenerate 974-col decorative single line
that isn't grid art and doesn't need exact alignment).
