Reapply "Change test_module_config from copying files to symlink ..."

This reverts commit c6a321e4dee7ce2a832a9308ab4c7279a1cd0dfb.

Original commit broke whe building sdk/ndk in postsubmit because of
missing target arch.

See: https://android-build.corp.google.com/artifact/submitted/11914755/mainline_modules_sdks-trunk_staging-userdebug/latest/view/logs%2Fbuild_error.log

Reapplying originaly commit and adding fix in patchest.
