[PATCH v2] submodule sync: Update "submodule.<name>.url"

[David Aguilar <davvid@gmail.com>]

When "git submodule sync" synchronizes the repository URLs
it only updates submodules' .git/config.  However, the old
URLs still exist in the super-project's .git/config.

Update the super-project's configuration so that commands
such as "git submodule update" use the URLs from .gitmodules.

Changes since v1:
We now call clear_local_git_env after configuring
the super project (thanks Johannes).
