[PATCH] environment.c: add GIT_NAMESPACE to local_repo_env

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This environment variable is added in a1bea2c (ref namespaces:
infrastructure - 2011-07-05). This is clearly repo specific setting
and should not be propagated to subprograms.

In practice, this is not a problem because GIT_NAMESPACE seems
designed for use on the server side and while submodule traversal
stuff happens on the client side.
