ecore_drm2: Use correct drm context version

We should be setting this to the context version we understand, not
the highest version supported by the library.

From Daniel Stone's recent intel-gpu-tools commit fixing the same bug:
With libdrm 2.4.78, setting a higher context version than 2 will attempt
to call the page_flip_handler2 vfunc if it was non-NULL, which being a
random chunk of stack memory, it might well have been.
