Add DeviceProfile dump files into artifacts

Artifacts are collected from:

    <metrics_collector class="com.android.tradefed.device.metric.FilePullerLogCollector">
        <option name="directory-keys" value="/data/user/0/com.google.android.apps.nexuslauncher/files" />
        <option name="collect-on-run-ended-only" value="true" />
    </metrics_collector>

Defined in NexusLauncherTests.xml, by writing the files into that
directory the files should show in the artifacts section when a
test fails.
