Ignore consume-aar with m2e

Unfortunately the consume-aar goal of the maven-android-plugin is not
supported by m2e-android. Since every goal have to be mapped to eclipse
plugins, the functional test project cannot be built with eclipse. This
commit addresses this issue by simply ignoring the goal since that does
not affect our project.
