ANDROID: kleaf: export get_kunit_modules_superset from modules.bzl

get_kunit_modules_superset() returns the full superset of KUnit module
paths as a plain list (no select()), making it safe to call at Bazel
load time. Re-export it from the public modules.bzl so downstream
can use it to auto-derive KUnit module lists without duplicating
or manually syncing the list.
