[Cogl] [PATCH 1/2] Fixes for building with --disable-gl

[Neil Roberts]

This fixes a few problems that occur when only using a GLES2 header.

• The use of GL_CLAMP_TO_BORDER and GL_MIRRORED_REPEAT were moved from
  cogl-pipelinelayer-state.h to cogl-sampler-cache-private.h but the
  corresponding defines were not.

• cogl-sampler-cache.c was using GL_TEXTURE_WRAP_R but this is only
  defined as GL_TEXTURE_WRAP_R_OES from the GLES2 header so it needs a
  #define.

• cogl-framebuffer-private.h uses GLuint but it does not include
  cogl-gl-header.h. It gets away with this when GLX support is enabled
  because the GL header would be included via glx.h.
