do not require git installed in order to use wraps

It doesn't make sense to check for the presence of git every time we use
it, but short-circuit any attempt to use a wrap right from the get-go
because we are trying to be fancy with submodules.

If git is not installed, simply do not try to figure out whether the
wrap is a submodule that can potentially be checked out/updated for the
user. Just take it on faith that it isn't one.

Fixes #2623
