externalsrc: Detect code changes in submodules

Browse Source 
Further to 50ff9afb39, only detect code changes in submodules that are
subdirectories of the EXTERNALSRC directory.

The (undocumented) git submodule--helper returns a path
for each submodule relative to the top of the repo.
Don't add submodules that are not within our source subtree.

[YOCTO #14333]
