perf: Fix undefined PyVarObject_HEAD_INIT in python 2.5

PyVarObject_HEAD_INIT is undefined in python 2.5, resulting
in a build crash:

util/python.c:81: attention : déclaration implicite de la fonction « «PyVarObject_HEAD_INIT» »
util/python.c:82: erreur: request for member «tp_name» in something not a structure or union
util/python.c:117: erreur: request for member «tp_name» in something not a structure or union
util/python.c:146: erreur: request for member «tp_name» in something not a structure or union

util/python.c:532: erreur: request for member «tp_name» in something not a structure or union
util/python.c:761: erreur: request for member «tp_name» in something not a structure or union
error: command 'gcc' failed with exit status 1
make: *** [python/perf.so] Erreur 1

We can fix that by defining PyVarObject_HEAD_INIT as a wrapper on
PyObject_HEAD_INIT, thanks to a trick found on biopython:
