[Buildroot] [PATCH v4 2/2] package/efl: add Wayland support

[Romain Naour <romain.naour@gmail.com>]

The EFL Wayland support was removed with commit [1] since the dependecy
on libdrm was missing. Also it requires OpenGL ES with EGL, Evas DRM
and Evas GLES DRM support [2].

As stated in configure, Evas GLES DRM engine support (gl_drm) depends
on wayland-client to build (wayland-client >= 1.8.0).

So, enable gl_drm only when wayland support is selected.
