Convert maven-checkstyle-plugin run to ant run

[rnveach]

Similar to checkstyle/contribution#273 and checkstyle/checkstyle#5385 ,

We need to deprecate all usage of maven-checkstyle-plugin so we can start implementing backward breaking changes.

There should be no breaking change here as main repo does not do regression on this repo.
