[SPARK-13050][BUILD] Scalatest tags fail build with the addition of the sketch module

A dependency on the spark test tags was left out of the sketch module pom file causing builds to fail when test tags were used. This dependency is found in the pom file for every other module in spark.

Closes #10954 from ajbozarth/spark13050.
