Revert poor tolerance roads and boundaries

[nvkelso]

When loading 512px tiles in MapboxGL versus Tangram there is a noticeable "off by one" geometry simplification level of detail difference for some layers, like roads and boundaries.

In #1718 we changed the tolerance for roads and boundaries layer to 2.0 from 1.0 to get a little bit smaller tile size. In retrospect the file savings were negligible but the visual effect is compounded in MapboxGL and should be reverted.

• vector-datasource/queries.yaml

  Line 217 in 0a760a1

  tolerance: 2.0

  Line 290 in 0a760a1

  tolerance: 2.0

Just to clarify, rendering on these is the same in Tangram and Mapbox GL (both adhere to the 512px tile approach for these tiles).

Fixed via #1988.
