pyuno: remove obsolete LC_NUMERIC to "C" mangling code

The CPython changelog says for version 2.4:

- Python no longer relies on the LC_NUMERIC locale setting to be
  the "C" locale; as a result, it no longer tries to prevent changing
  the LC_NUMERIC category.

(cherry picked from commit 1ee5e1a1)
