util/gitconfig: Update `sup-destroy` git alias

The `git sup-destroy` alias uses a subshell in order to make `git
submodule deinit` deinitialize all submodules. This isn't necessary as
the `--all` switch does the same.

Furthermore, `git submodule init && git submodule update` equals to `git
submodule --init`.
