python: drop redundant function

I noticed some redundant code while preparing my next patch.

* python/generator.py (py_types): Fix 'const char *' mapping.
* python/typewrappers.h (libvirt_charPtrConstWrap): Drop.
* python/typewrappers.c (libvirt_charPtrConstWrap): Delete, since
it is identical to libvirt_constcharPtrWrap.
