gl/context: move egl creation lower in priority on _new()

e.g. if running a dual wgl/egl built library, then egl will always
succeed in creating the GstGLContext because almost anything could
support egl, as long as eglGetDisplay() works.

wgl, however has a check for the correct display type so should move
earlier in the tried list.
