[SPARK-9045] Fix Scala 2.11 build break in UnsafeExternalRowSorter
This fixes a compilation break in under Scala 2.11:
```
[error]
/home/jenkins/workspace/Spark-Master-Scala211-Compile/sql/catalyst/src/main/java/org/apache/spark/sql/execution/UnsafeExternalRowSorter.java:135:
error: <anonymous org.apache.spark.sql.execution.UnsafeExternalRowSorter$1> is
not abstract and does not override abstract method
<B>minBy(Function1<InternalRow,B>,Ordering<B>) in TraversableOnce
[error] return new AbstractScalaRowIterator() {
[error] ^
[error] where B,A are type-variables:
[error] B extends Object declared in method
<B>minBy(Function1<A,B>,Ordering<B>)
[error] A extends Object declared in interface TraversableOnce
[error] 1 error
```
The workaround for this is to make `AbstractScalaRowIterator` into a
concrete class.
