package/efl: enable libdrm support

drm can be used without compositor, just like it was with
the framebuffer for standalone applications

As stated in configure.ac, libdrm support needs libdrm, elput,
libxkbcommon and libgbm.

libgbm is only provided by mesa3d package when OpenGL EGL support is
enabled, so add a direct dependency on mesa3d.

Rework the libxkbcommon dependency since it's now required for
elput and libdrm support.
