hooks-enabled: don't call submodule-update.sh from hooks for now

In the current setup executing git submodules commands from 'vcsh run'
invocations would fail because the '.gitmodules' file would not be
checked out.

For now it's only safe to call git submodules commands after entering
the repository with 'vcsh enter'.
