[PATCH weston 2/3] gl-renderer: check EGL_EXT_platform_base in supports()

[Pekka Paalanen]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

An EGL implementation may support client extensions without supporting
EGL_EXT_platform_base. In such a case, we should return 0 to fall back
to the old eglGetDisplay() way.
