use less-than instead of not-equal when comparing key sizes ( #242 )
...
When evaluating policy compliance, use less-than operator so keys bigger
than expected (and hence very often better) don't fail policy
evaulation. This change reduces the amount of false-positives and allows
for more flexibility when hardening SSH installations.
