modify-python-lldb.py: Remove docstring formatting code

The strings have been already cleaned up in r358683, so this code is not
doing anything anymore.

While comparing the outputs before and after removing the formatting
code, I've found a couple of docstrings that managed to escape my perl
script in r358683, so I format them manually with this patch.
