[Buildroot] [v3,2/2] package/efl: add Evas GL DRM Engine support

[pierre floury <devpfl@gmail.com>]

From: Romain Naour <romain.naour@gmail.com>

This support is required for Enlightenment wayland support [1].

As stated in configure, Evas GL DRM Engine needs OpenGL ES with EGL and
wayland (wayland-client >= 1.8.0)
