tests: split example_filesystems into its own package
Running these tests from integration_tests' TestMain() was awkward because they were run twice with unchanged settings. integration_tests tests everything with OpenSSL and with native Go crypto, but this does not take affect for the example filesystems. To make this work, test_helpers is also split into its own package.
