[Piglit] [PATCH 2/2] gl-1.0-beginend-coverage: fix FBO-related failures when using GLUT

[Brian Paul]

When Piglit's configured to use GLUT instead of Waffle we don't have
full support for the -fbo option.  So in beginend-coverage we now
check if we really have a FBO bound in order to compute the right
fbo_attachment value.
