Fix simple bazel build_rules cases of rules returning struct

This is a migration step toward #7347 , so that Starlark rule implementation functions no longer return struct.
Not all usages are migrated: cases where a struct is returned with a "custom" field name requires more migration care.
See #7347 for details.

RELNOTES: None.
