Neil Roberts 7adf7c5e38 kms: Fix GLES2 support
There were two problems stopping the KMS winsys from working with a
GLES2 driver:

• When creating the EGL context, it was missing the attribute to
  select the client version so it would end up with the GLES1 API.

• When creating the depth buffer for the framebuffer it was using
  GL_DEPTH_COMPONENT but only GL_DEPTH_COMPONENT16 is supported on
  GLES. cogl-framebuffer already unconditionally uses this so it
  probably makes sense to do the same here.
