Git already supports that use case: Just set the "submodule.<name>.update"
configuration to "none" for all submodules you aren't interested in and
"git submodule update" will always skip them.

You can also set this config option globally:

git config --global submodule.<name>.update=none

That'll set the default for all repositories of the logged in user on this
computer to not update submodule <name>.

git clone will be influenced by the global setting. If you just want to
skip submodule <name> for a single clone you can do it like this:

   git -c submodule.<name>.update=none clone --recursive git://github.com/foo/bar.git
