Cleanup dynamically allocated memory before exit in tests

Cleanup dynamically allocated memory before exit in tests in a few
places where missing. While such cleanups right before exit do not
usually make much sense (as the operating system would cleanup anyway,
so manual cleanups only burn CPU cycles), we will want to catch any
potential problems in libunwind related to the cleanups. This also stops
valgrind complaining about unreleased memory.
