From: John Edward Broadbent <jebr@google.com>

Git has removed support for "git submodule--helper list".
https://github.com/git/git/commit/31955475d1c283120d5d84247eb3fd55d9f5fdd9

This change provides an alternate method for gathering the submodules
information.

Tested:
Build recipes with and without submodules

(cherry picked from commit 6d9364e5f3535954f65cbbc694ee7933ac1d664f)
---

Notes:
    With git 2.38.0 externalsrc does not work anymore. I hope, we can
    backport this fix to stable branches as well.
