Summary:
KWin was quite good in ensuring that you don't need to install by
passing paths to the tests. The new way is much nicer, so code is
adjusted for the new way. Also if we require a newer ECM in future we
need to support the new way.
No guarantee that the tests don't pick something up from the system env,
that needs more testing.

Differential Revision: https://phabricator.kde.org/D7543
Removes one of the last pure XLib usages and also means that in theory
we can detect the Xwayland version number. In practice that only works
when restarting the compositor as detect is invoked before the XWayland
connection is created.
The new test can load "profiles" from kconfig files in the test data.
Based on that the glGetString return values are mocked and GLPlatform
can perform detect without having to interact with a real GL library.
That way we can verify that the detect code works correctly. As a first
test the settings of one Intel/IvyBridge is included. More tests can be
added easily (e.g. looking at various supportInformation output in
bugs.kde.org). Also this allows to more easily add detect code for GPUs
we do not know yet. And to simulate conditions where the detect code
failed resulting in no compositing at all.
