If diff command fails then use difflib.unified_diff() to generate diff.

* tools/hook-scripts/mailer/mailer.py

 (DiffGenerator.__getitem__): Fall back to difflib.unified_diff()

  if native 'diff' fails.

 (_classify_diff_line): New function taken from DiffContent.__getitem__()

  for reuse by the new class DifflibDiffContent.__getitem__().

 (DifflibDiffContent): New diff generator using difflib.
