Allow use of checkstyle outside of main PRESUBMIT.py

Allow use of checkstyle outside of main PRESUBMIT.py

This commit allows the use of checkstyle outside of the main PRESUBMIT
script in src. Since checkstyle can possibly be called from a subfolder
of src the absolute path to the java files are used instead of relative
to src.

We also honor the EXCLUDED_PATH blacklist for Java files.
