[ADAM-1307] move_to_spark_2 fails after moving to scala 2.11.

The sed command that moved to Spark 2 looked for _2.10 in the
ADAM pom artifact names. This commit fixes that issue by looking
for _2.1 instead, which matches both Scala 2.10 and 2.11, as well
as the eventual Scala 2.12. Resolves #1307.
