mesa: make the number of draw buffers part of the texenv program key state

All the state that effects the program should be in the key.
This didn't help with bug 28169 but is a good fix anyway.

NOTE: this is a low-priority candidate for the 7.8 branch.  In practice,
this issue might never be hit.
