[Filesystem] fix tests on 2.3

Christian Flothmann · Christian Flothmann · commit 9050f676af5f · 2015-12-19T12:15:11.000+01:00
The test introduced in #16797 used the `assertFilePermissions()` method to test for the expected result. This worked quite well for the PR as it was submitted for the `master` branch. However, the tests now fail on 2.3 as the `FilesystemTestCase` class which contains this method was introduced with Symfony 2.4.
