git-submodule.sh: shorten submodule SHA-1s using rev-parse
Until now, `git submodule summary` was always emitting 7-character SHA-1s that have a higher chance of being ambiguous for larger repositories. Use `git rev-parse --short` instead, which will determine suitable short SHA-1 lengths. When a submodule hasn't been initialized with "submodule init" or not cloned, `git rev-parse` would not work in it yet; as a fallback, use the original method of cutting at 7 hexdigits.
