travis-build.sh: use maven.imagej.net as mirror

ctrueden · ctrueden · commit 8e08b084325a · 2018-08-30T16:38:45.000-05:00
When maven.imagej.net is defined as a repository in the POM, add
it as a mirror in the settings.xml, to avoid Maven Central issues.

This might be a bad idea, but we'll give it a try.
