replace: use a GIT_NO_REPLACE_OBJECTS env variable
This has the same effect as --no-replace-objects option; git ignores the replace refs. When --no-replace-objects option is passed to git, this environment variable is set to "1" and exported to subprocesses in order to propagate the same setting. It is useful for example for scripts, as the git commands used in them can now be aware that they must not read replace refs.
