[libvirt] [PATCH] build: avoid python 2.4 build failure

[Eric Blake]

On RHEL 5, I got:

/usr/bin/python ./generator.py /usr/bin/python
  File "./generator.py", line 427
    "virStreamFree", # Needed in custom virStream __del__, but free shouldn't
                   ^
SyntaxError: invalid syntax

* python/generator.py (function_skip_python_impl): Use same syntax
as other skip lists.
---

Pushing under the build-breaker rule.  However, the build is still
broken on RHEL 5, due to this next one that I don't know how to fix
(probably we'll have to test in configure.ac whether Py_ssize_t
exists, and if not, typedef it ourself in libvirt-override.c):

In file included from libvirt-override.c:22:
typewrappers.h:159: error: expected declaration specifiers or '...' before 'Py_ssize_t'
