gles2: Honor alpha in fragment_src_external

Browse source 
By using the same vertex shader and adding alpha to the fragment shader
for external textures we can:

  - use alpha blending
  - have wlr_gles2_render_texture_with_matrix work with
    the GL_TEXTURE_EXTERNAL_OES. So far this failed
    since we passed in alpha which was unknown by fragment_src_external
