Previously, the cfg attribute `cfg(not(a, b))` was translated to `(!a && !b)`, but this isn't very useful because that can already be expressed as `cfg(not(a), not(b))`. This commit changes the translation to `!(a && b)` which is more symmetrical of the rest of the `cfg` attribute. Put another way, I would expect `cfg(clause)` to be the opposite of `cfg(not(clause))`, but this is not currently the case with multiple element clauses.
