Remove code cache check from native bridge run-test

Every now and them the native bridge run-test failed because the code
cache cannot be found. I suspect a temporary I/O issue when stat-ing the
directory. However I could not verify yet that's actually the cause.

Native bridge can work without a code_cache so we can relax the test
until we figure out the flakiness.
