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.
