Ævar Arnfjörð Bjarmason 26a15355d6 difftool: use "env_array" to simplify memory management ...

Amend code added in 03831ef7b5 (difftool: implement the functionality
in the builtin, 2017-01-19) to use the "env_array" in the
run_command.[ch] API. Now we no longer need to manage our own
"index_env" buffer.
