glapi: Reformat python code generation scripts to use 4-space indentation.

This brings us into accordance with the official Python style guide
(http://www.python.org/dev/peps/pep-0008/#indentation).

To preserve the indentation of the c code that is generated by these
scripts, I've avoided re-indenting triple-quoted strings (unless those
strings appear to be docstrings).
