Ignore the Maven wrapper files in the license check

Description

The Travis builds fail with the latest version of the Maven wrapper because the wrapper now downloads a source file in the .mvn directory.

This directory should be ignored.

I opened an issue (https://github.com/takari/maven-wrapper/issues/72) in the Maven wrapper tracker as it doesn't seem like a normal behavior.

Anyway, it's safer to completely ignore this directory.
