[Debug] Replaced logic for detecting filesystem case sensitivity 
When I cloned the master branch onto a Virtualbox Vagrant OSX El Capitan host, Ubuntu Wily guest, the `Symfony\Component\Debug\Tests\DebugClassLoaderTest::testFileCaseMismatch` failed because 'Failed asserting that exception of type "\RuntimeException" is thrown'.

@wouterj confirmed he got the same problem, and it's because Virtualbox shared folders aren't case sensitive, even when the guest is using a case sensitive filesystem. So I've replaced the logic that looked at the name of the operating system.

I ran the tests in the following environments:
* Virtualbox/Vagrant - OSX Host, Ubuntu guest
* Virtualbox/Vagrant - OSX Host, Windows guest
* OSX native
* Ubuntu native

NB - I _didn't_ run it on native Windows (because I don't have easy access to one).
