[Piglit] [v4 01/11] arb_transform_feedback3: add test for buffer binding with invalid index

Passes on NVIDIA (304.88 on GTX 660) and on Ivy Bridge.

v2 (Ian):
   - ask the driver the maximum amount of streams supported
     instead of treating 'GL_MAX_TRANSFORM_FEEDBACK_BUFFERS' as the
     value.
   - keep on trying the different combinations even if one of them
     fails.
   - try also maximum allowed for success
   - used size 'sizeof(GLfloat)' instead of '1' for
     'glBindBufferRange()'. Otherwise even the positive case of
     maximum supported fails on NVIDIA.
