[SPARK-8693] [PROJECT INFRA] profiles and goals are not printed in a nice way

Hotfix to correct formatting errors of print statements within the dev and jenkins builds. Error looks like:

```
-Phadoop-1[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  -Dhadoop.version=1.0.4[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  -Pkinesis-asl[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  -Phive-thriftserver[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  -Phive[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  package[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  assembly/assembly[info] Building Spark (w/Hive 0.13.1) using SBT with these arguments:  streaming-kafka-assembly/assembly
```
