i965: glClearBuffer() should only clear a single buffer.
glClearBuffer() is currently clearing all active draw color buffers (all
buffers that have not been set to GL_NONE when calling glDrawBuffers) instead
of only clearing the one it receives as parameter. Altough brw_clear()
receives a bit mask indicating the color buffers that should be cleared,
this mask is ignored when calling brw_blorp_clear_color().
This was breaking the 'fbo-drawbuffers-none glClearBuffer' piglit test.
The patch provides the bit mask to brw_blorp_clear_color() so it can limit
clearing to the color buffers present in the mask.
