CYA: pre-remove output files in jenkins-test

while debugging jenkins-test runs, I copied some of the files it
generates into my local ADAM_HOME; these were in turn getting copied
into the tmp dir created by jenkins-test, and causing various commands
to fail when they realized the path they were trying to output to
already exists. This seems like an unnecessary failure mode for the
jenkins-test script to be vulnerable to (namely, the existence in local
ADAM_HOME of files (untracked by git) with the same names as arbitrary
paths that jenkins-test expects to write to), especially since these
particular files are involved in tests but don’t actually live in the
git repo.
