[cleaner] Stop obfuscation of gz files when using --keep-binary-files

[jcastill]

This commit tries to honour option --keep-binary-files when using cleaner
by making sure that these files are skipped so the cleaner
doesn't attempt to apply substitutions directly on them.

This should be using file_is_binary(), as we're explicitly saying keep binary files.
