checker-framework.groovy (generate): no output on Linux

[rnveach]

When running groovy ./.ci/checker-framework.groovy checker-framework-nullness-optional-interning -g on linux, I get no XML output when I am expecting the tool to generate the new suppression file for me. It just ends with a build success.
Below is output:

First issue seems to be the groovy script requires the top checkstyle folder of source to be named checkstyle.
https://github.com/checkstyle/checkstyle/blob/master/.ci/checker-framework.groovy#L164
In this case, my folder was named checkstyle2 as this process takes a while to run and was starting to use 2 cloned repos to speed things up.

I don't think should be a requirement. We should look instead for src/(it|main|test)/java.

New location of hardcoded folder name

checkstyle/.ci/checker-framework.groovy

Line 170 in c6005cb

.compile(".*[\\\\/](checkstyle[\\\\/]src.*\\.java):\\[(\\d+)[^]]*][^\\[]*\\[([^]]*)](.*)")

I think we can simply remove this reference, I don't think we will have files other than in our repo in plugin output.
