Merge of #373 prevents Building pi4j on a Pi.

[taartspi]

@eitch @FDelporte I did a fetch and rebase and then mvn clean install -Pnative.
Failures:
[ERROR] AutoPlatformsTest.testPlatformsNotEmpty:69 expected: but was:
[ERROR] Errors:
[ERROR] I2CRawDataTest.testRawDataStream:148 » Pi4J Failed to execute action for devic...
[ERROR

In the file DefaultContextBuilder line 54 protected boolean autoDetectMockPlugins = !BoardInfoHelper.runningOnRaspberryPi();
I set this to true and the build and test works.
I did no further investigation @eitch thinking your suggestion of how to change #373 is needed.
