[PATCH] Revert "git.el: Set process-environment instead of invoking env"

["Karl Hasselström" <kha@treskal.com>]

This reverts commit dbe48256b41c1e94d81f2458d7e84b1fdcb47026, which
caused mis-encoding of non-ASCII author/committer names when the
git-status mode is used to create commits.

In case no one who understands how, why, and whether the fix works
comes forward, here's a revert of the commit that introduced the
