util/scripts: Add options to update_submodules

This extends and adds various options to the update_submodules script.

Extensions:
- Add help text
- Add all options, but specifically allow a single repo to be specified,
along with a minimum number of changes instead of being fixed at 10.
- Make it a more formal script with main() and functions
- Show changes in commit message, unless there are > 65 commits.

Options:
-c | --changes <#>     Specify the minimum number of changes to update a repo
-h | --help            Print usage and exit
-R | --repo <dir>      Specify a single repo directory to update
-s | --skipsync        Assume that repos are already synced
-V | --version         Print the version and exit

This does not fix style issues in the original, which will be fixed in
a follow-on commit.
