Add more info to message logged when a duplicated symlink file is fou…

…nd (#10845)

There was a typo in the message that was logged when symlinks are enabled and the same files are found. I also added more context to the message, so it is more informative.
The new message is the following:

Same file found as symlink and original. Skipping file: test.log (as it is same as: test-2016.log)
