bitbake: gitsm: tolerate git-lfs in submodules

Explicitly pass down the lfs parameter from the source repo URI to
submodules. Add smudge skip to final checkout phase to make sure we
don't access the network here. Everything should have been fetched and
setup from the lfs logic in the git fetcher at this point.
