Make timezone lookup a bit more clever

If we don't find a timezone at the given coordinate, check the
surroundings. This helps with locations close to the coast, where
due to rounding/anti-aliasing we hit water initially.

This reduces the remaining timezone lookup failures from 125 to 89, for
the ~7700 airports.
