If the driver doesn't support the getfb iface (e.g. because KMS has been
disabled), the ioctls will fail with ENOTSUP. This is expected, so skip
the test as nothing useful can be learnt.

Make sure we gently skip when required features (CCS, getfb2) are not
supported on the running kernel, and clean up properly after ourselves.

We'll want to reuse this, so split it out into a (smaller!) helper.

The getfb ioctl only supports returning a single buffer handle
(mirroring addfb), which means it should refuse to return us back CCS
buffers.
This is enforced by the kernel as of b24791fe00f8.

Add a new test exercising the GetFB API, specifically including its
behaviour of always returning new handles even if the client already has
a handle to the GEM buffer.
