Default NVidia EGL to GLES2
Found some documentation saying NVidia provided desktop GL for
development purposes only, and recommmended against using it. Not sure
if that applied to all NVidia drivers, or only that one embedded
platform, but since we have multiple bugs about EGL not working on
NVidia, default to using GLES2 like it suggested.
