Assert using realpath when confirming "env".

On the Infra 32-bit Trusty builder, this caused a problem because the
THIRD_PARTY was resolving to a symlink directory, but the importer was
importing using the symlink-resolved path. Fix this by improving the
assertion to specifically care that the realpath matches.
