tests: use NO_CHECK_EOF for fragments having intentional error

Some test scripts are excluded in test-check-module-imports.t, because
import-checker.py reports that code fragments embedded in these test
scripts have syntax error. But these syntax error is intentional.

This patch uses NO_CHECK_EOF instead of EOF as heredoc limit mark for
such fragments, in order to make import-checker.py ignore
them. NO_CHECK_EOF limit mark tells import-checker.py that this code
fragment should be ignored, via testparseutil.py.
