chore(util) always install SDK example test cases

Add a new `--install` mode to sdk.sh for copying the compiled .wasm
filters, if any. Now test.sh always installs SDK test filters, if any.

This allows `make cleanup` to properly clean the work/lib/wasm directory
and subsequently run `make test` again.
