bitbake: data: Ensure dependencies of subfunctions are accounted for

Currently we account of the top level function's vardeps but not
those of any subfunction. This would imply we'd have to manually
write the dependencies of all parent functions which would be crazy.

This patch adds the dependencies to fix the issue.
