This changes the Suggestions to be a single column, not a wrapping row,
changing the input to be incapable of overflowing into visually adjacent
elements.
There's already precedence for not using GNUism sha256sum longopts as
seen in searxng/utils/lib_go.sh so update lib.sh to not use them either.
A nice side effect is now the sha256sum usage doesn't care if you're
using BSD sha256sum or GNU sha256sum which makes this work under FreeBSD.
