cros clean: fix debugging error

The debug message for handling bind mounts uses an invalid variable:
...
  File ".../chromite/cli/cros/cros_clean.py", line 142, in CleanNoBindMount
    self.options.path)
AttributeError: 'ArgumentNamespace' object has no attribute 'path'

Linting didn't notice it because the argparse options are dynamically
constructed.  It failed on my system because I have a bind mount.

Also improve the debug cros error message to tell people to try
using --debug to get a full traceback.

BUG=chromium:764067
TEST=`cros clean --safe` works again
